First there was the laptop. Then the notebook. The netbook is the most recent addition to mobile devices with hardware keyboards. That is, until today. Google has officially launched a new cloud OS based mobile device dubbed the ChromeBook.
As a netbook with an operating system that amounts to little more than a web browser, the device purports to not only match the functionality of a "normal" netbook, but surpass it thanks to file storage residing in the cloud, automatic updates to the OS, virtually unlimited applications, and an eight second boot time.
Google further states that the device is capable of all the promises feats while remaining secure. Security is accomplished by several independent strategies. The OS splits up system settings and user settings, and each ChromeBook allows only one "owner" per device. The owner is able to allow other users to log in to the device as well, whether it is with their Google account or as a guest. Guest Mode does not sync or cache data, and all system settings are kept out of the session, including network configuration. Each process is sandboxed in an effort to reduce the likely hood of cross-process attacks. Further, the browser and plugin processes are not given direct kernel interface access. Toolchain hardening seeks to limit exploit reliability and success. The file system has several restrictions, including a read-only root partition, tmpfs-based /tmp, and User home directories that can not have executable files.
Further, ChromeBooks utilize a secure automatic update system and Verified Boot that seeks to eliminate attacks tampering with the underlying code. All updates are downloaded over SSL, and are required to pass various integrity checks. The version number of updates is not allowed to regress, meaning that only updates with a version number higher than those already installed on the system are allowed to install. Further, on the next boot-up, the updates undergo a further integrity check in the form of what Google calls "Verified Boot."
According to Google, Verified Boot "provides a means of getting cryptographic assurances that the Linux kernel, non-volatile system memory, and the partition table are untampered with when the system starts up." The process depends on a "chain of trust" which is created using custom read-only firmware rather than a TPM (Trusted Platform Module) device. The read-only firmware checks the integrity of the writable firmware, and if it passes then the writable firmware is used to check the integrity of the next component in the boot up process. While Verified Boot does not protect against dedicated attackers, it does allow a safe recovery option when re-installing as well as detecting changes made by a successful run-time attack and files or write-able firmware changes made by an attacker with a bootable USB drive.
In future iterations of the OS, Google is pursuing driver sandboxing as well as implementing a secure method for auto-logins. Further, Google states that they are interested in pursuing biometric security if they are able to ensure their authentication software is secure when using low cost hardware. Also on the agenda is implementing a "single signon" system that would allow users to log into third party sites using credentials generated by their Google account.
Hardware running Chrome OS is not new, however. Google's CR-48 notebook has been in the wild for months, allowing thousands of users the chance to try out the new operating system and its accompanying hardware. Both Acer (11.6", $349) and Samsung (12.1", $429 wifi only) have stepped up to the plate and are offering ChromeBooks at launch. What is new; however, is the way in which users are able to purchase the hardware. While consumers will still be able to purchase a ChromeBook from retailers, Google has announced a new subscription option for school and business users. The new subscription service would allow students to receive a ChromeBook for $20 a month, while business users would pay $28 a month. In order to get the subscription price schools and businesses must enter into a three year contract. The subscription price includes the "hardware, operating system, updates and cloud-based management" along with online, email, and telephone support directly from Google. The monthly subscription further includes regular hardware refreshes.
It is apparent that Google sees its largest market for ChromeBooks as being large businesses and schools, which can then manage a fleet of ChromeBooks for their users for a much lower cost versus maintaining hundreds of traditional computers. While large IT departments are likely to see the cost benefits, It remains to be seen how consumers will react to this subscription based model. Subscriptions have become more prevalent, with the majority of the US using cell phones with monthly contracts. On the other hand, users --students especially-- are used to buying a computer outright. Will the lure of low cost subscription ChromeBooks be enough to break consumers' traditional thoughts on purchasing computers? Will students accept remotely administrated computers in exchange for a low cost subscription?

Gigabyte recently announced in a press release a new ultra light notebook aimed at business users. More specifically, they unveiled the Gigabyte GS-AH6G3N, which is a laptop that purports to support the latest technology. According to the press release, the ultra light laptop brings to the table support for both Sandy Bridge processors and up to 8GB DDR3 RAM. A fingerprint reader and TPM module are also available for the security conscious. The 14" and less than 4.5 pound (2 kilogram) notebook is very sleek looking with sharp and clean lines detailing a dark black or silver body.
As a business notebook, it uses the Intel Mobile HM65 Express chip set, which means that you are looking at using the integrated processor graphics contained in the Core i 2xxx chips. To the road warriors' comfort, the integrated graphics should provide longer battery life while still running Windows 7’s Aero desktop smoothly. Another touted feature is the inclusion of USB 3.0 ports which will help in keeping large amounts of data backed up. An included HDMI port should help to sway business users who need to connect to projectors and large displays for their work in its favor (a VGA port is provided as well, for older projectors.)
The full specifications that Gigabyte list are as follows:
|CPU||LGA 1155 socket, Intel® Core™ i7 / Core™ i5 / Core™ i3 processor|
|OS||Microsoft Windows 7|
|Display||14" LED Backlit at 1366x768 pixels|
|RAM||DDR3 (2 slots) up to 8GB|
|Chipset||Intel Mobile HM65 Express|
|Graphics||Intel HD 3000|
|Hard Drive||Sata 2.5", 9.5mm drivers. Up to 750GB|
|Optical Disk Drive||(Optional) 9.5mm Super Multi DVD-RW|
|I/O||2xUSB 3.0, 2x USB 2.0, 1x HDMI, 1x VGA, RJ45, Mic-in, headphone-out, DC-in, docking connector, and 3-in-1 card reader (SD,MMC,Memory Stick)|
|Audio||2x 1.5watt stereo speakers|
|Communications||Gigabit Ethernet, 802.11 b/g/n WIFI, Bluetooth v3.0 + EDR (Wifi/BT Combo)|
|Webcam||1.3 megapixel camera + microphone|
|Security||Kensington lock, Fingerprint reader, and optional G-sensor and TPM|
|Battery||6-cell Li-Ion 2600mAh 60WHr (claimed 7 hours of battery life)|
|Dimensions||338 (W) x 235 (D) x 26.0 (H) mm|
|Weight||~2kg (with DVD drive and 6 cell battery), ~4.49 lbs|
|Color||Silver / Black|
Unfortunately for business users in the United States, Gigabyte branded notebooks can be a bit difficult to purchase as they are generally sold overseas. Once this laptop has been on the market for a few months, they do start to trickle over into the US markets. For overseas readers of PC Per; however, the Gigabyte notebook may be something to consider as in the end it shapes up to be a powerful but small notebook that should work well for those that need to travel light and fast for their business.
Introduction and Design
The last three years have been great for ultraportables and netbooks. Laptops with displays below fourteen inches in size have exploded in popularity thanks not only to Intel's Atom, but also a wide selection of Intel ultra-low voltage products. Many of the laptops that we've reviewed over the past year, such as the Lenovo IdeaPad U260 and the Alienware M11x, would have been impossible prior to the release of those processors.
Mainstream laptops have enjoyed less progress, however. The 15.6" laptop remains the most popular category with consumers, but while it has enjoyed a boost in performance with the release of the original Core i series processors, issues like battery life and graphics performance remained largely unaddressed. These mainstream laptops have continued to represent a major compromise, as they've been unable to provide great battery life but also (unless supplimented with a discrete GPU) lack the chops to play any but the most basic 3D games.
According to Intel, these flaws could soon be addressed. Intel's Sandy Bridge mobile processors are nothing short of the savior of mainstream laptops. These processors not only offer the typical improvements in speed but also drastically improved integrated graphics and provide much better battery life.
Or, at least, that's what Intel says. They've said such things in the past, however - Intel's IGPs have often promised more than they can deliver. But every piece of hardware deserves a fair shake, and now it's time for Intel's Sandy Bridge to step up to the plate, appearing today in the form of the ASUS K53E. Let's see what is under the hood.

The Acer Iconia 6120 is a little like a Nintendo DS, in that where you would expect input buttons you have another LCD. Powered by an Intel Core i5 480M, an HM55 with IntelHD graphics powering the two 14" 1366 x 768 displays. Benchmark Reviews demonstrates using it as both a dual display laptop and as a laptop screen and a touchscreen keyboard. Check it out.
"We've seen little innovation in laptop design in the last few years. Most companies seem to think that using a brushed aluminum finish or adding Intel's latest mobile CPU is all they need to do to freshen a product line. Still, Acer's not the first company to introduce a laptop with dual screens; the short-lived Toshiba Libretto W100 comes to mind, and gScreen Corporation's Spacebook has been touted since 2009, although it's still not available at the time of this writing. The Acer Iconia 6120, though, is a computer you can buy right now. Its dual screens offer new capabilities but come with some drawbacks as well. Benchmark Reviews takes a look at this unique laptop to see if it's worth your consideration."

Introduction and Design
Tech journalists are finicky beasts. A few years ago we were washing netbooks in praise, declaring that they promised a new era of accessibility and portability for the PC. But now the tables have turned – tablets have usurped the throne of “cool new thing” and tech news is all too eager to declare the netbook little more than a passing trend, soon to be booted out of the market by glorious touchscreen slates.
The truth, however, is not as extreme has the headlines suggest. Netbooks are another boring reality that won’t be going anywhere soon, despite declarations of death and injury. But I can understand why they’ve lost the limelight. The improvements made to netbooks over the last three years have been incremental at best. While battery life has gradually grown, performance has barely moved. Intel, lacking competition from AMD, has had little reason to improve its Atom processors.
Now AMD has finally brought an Atom competitor to the market in the form of its Fusion APUs. We already reviewed one laptop powered by Fusion, the Toshiba Satellite C655. That laptop, however, was equipped with AMD’s single-core E-240. It provided performance roughly on par with a dual-core Atom system we tested in 2010, but ultimately fell a bit shot of our expectations.
