Sony's T13 Ultrabook led a vanguard of traditional clamshells for the Windows 8 launch. The T15 Touch expands that line to a beefier model. The new model features the same aluminum and magnesium chassis, but since its larger, there's room for a numpad. The more spacious screen rocks a 1080p panel. Once it launches in the spring, you can snag this Core i5-equipped machine for $950.
