Lenovo has added a laptop to their ultra-portable notebook lineup.  The ThinkPad X1 features a Core i5 2520M CPU, 8GB of RAM, 160GB SSD and a 13.3-inch screen made from Gorilla Glass with a 1366×768 resolution. All of those features in a small 0.84-inch-thick package. The ThinkPad X1 also included a good keyboard and the great build quality we come to expect from the ThinkPad brand.

The bad news is the ThinkPad X1’s battery is sealed, meaning you will not be able to remove it yourself but the good news is the battery comes with a 3 year warranty and has a few replacement options. The battery can be replaced at a repair depot or Lenovo will have an on-site technician can come to replace the battery as early as the next business day. Lenovo clams the ThinkPad X1’s RapidCharge battery will last three times as long and will charge to 80% within 30 minutes.

With all of features the ThinkPad X1 has. Is it worth the $2900 price tag? You can buy a 13-inch MacBook Air for $1299 but, it’s unfair to judge the two of them by price alone because of the differences in processor, memory and hard drive size. Is a faster processor, more memory, larger SSD and a better battery warranty worth the extra cost?
