Toshiba Satellite U925T
At 3.2 lb. and sporting a 12.5-in., 1366 x 768 screen, the Toshiba Satellite U925t swaps between tablet and ultrabook mode via a sliding display mechanism that's a cousin to the one on the Vaio Duo 11. Packed with 128GB storage, 4GB RAM and a Core i5 processor, it also sports a slew of sensors for mobile use: three-axis gyroscope and accelerometer, GPS and NFC.
Front and back webcams, Intel Wireless Display and an HDMI port round things out. Note that the three-cell 38Wh battery is sealed in to keep the unit a slender 0.78 inches.
