Apple was famous for cramming as much PC hardware into a monitor as possible. At first, when the monitor was CRT-based, it looked weird. As monitors thinned, the computers became more classy. Leave it to the PC industry to fight over the smallest of details in order to get an edge over their competition. Several companies have been trying out various permutations of that idea and they sometimes hone in on one or more niches. Lenovo has four of these all-in-one PCs: the Horizon II, the N308, the A740, and the C560 Touch.

The Lenovo Horizon II is up first. We reviewed the original Horizon and Ryan enjoyed it for the 2 hours of battery life he was able to surf the web on. He found the tabletop design very fun to play Monopoly with friends on. Its performance was not too bad either (although Battlefield 3 and Bioshock Infinite are no-gos). The Horizon II gives the option of a resolution boost from 1080p to 1440p and, if you are not feeling particularly attached to your money: options for a Core i7 processor, 8GB of RAM, and a GeForce GTX 840A.

Maybe Battlefield is now… on the table… snicker snicker.

The Aura interface has been updated to version 2.0 and it interacts with phones via NFC. Speaking of mobile, the battery life is now expected to reach 4 hours per charge which would double what Ryan experienced if accurate. The Horizon II is also thinner and lighter with a weight of just 15.4 lbs which is over 3 lbs more light than the 18.95 lbs of the original Horizon.

The Lenovo N308 is a step in a different direction. This Android Jelly Bean 4.2.2 device includes an NVIDIA Tegra quad core processor with 2 GB of RAM. It has up to 3 hours of battery life and is a slightly more portable 19.5 inches (1600×900). It is still 10 lbs, though. It also has a gravity sensor which is great if you are playing a motion control game on this thing. No option for a wrist strap which is a blessing and a curse, I guess, when you're slinging around a 20-inch tablet? I think this is one of those things that will make more sense in person. Prices start at $449.

The Lenovo A740 is more like a typical all-in-one computer. Monitor, stand, up to a Core i7 processor, up to a GeForce GTX 800 series GPU, 1TB HDD. The 27-inch display has a 1440p resolution and 10-finger touch sensor. The stand can also dip significantly which allows for 100 degrees of tilt. Prices start at $1499.

Last, but not least, is the C560 Touch All-in-One PC. Starting at $549, it is Lenovo's budget all-in-one. It has a 23-inch 1080p touchscreen albeit one that can only track 5 fingers (which is still probably more than enough). You can give it up to 8 GB of memory and 2 TB of storage. All of this can be driven by a Haswell processor up to a Core i7 and an NVIDIA GeForce 705A 1GB GPU. The system is loaded with Windows 8.1. Nothing special with the stand. It stands up straight and looks interesting.
