Featuring a fanless design, this aluminum-clad detachable hybrid weighs a little over 2 pounds by itself, and about 4.5 pounds when connected to its keyboard dock. The X2 boasts a 13.3-inch 1920 x 1080 Radiance touchscreen, an Intel Core i3 or Core i5 Haswell processor and 4GB to 8GB of RAM. Storage options include a 64GB or 128GB SSD. By itself, the X2 should last up to 7.5 hours, and up to 10 with its keyboard. Starting at $1,099, this hybrid isn’t cheap, but it has the ingredients of a very versatile productivity device.
