It's also thinner than these devices, measuring 12.75 x 8.86 x 0.59 inches (324 x 225 x 14.9mm). With just the screen, the Surface Pro 4 weighs 1.69 pounds (766g) and the Surface Book comes in at 1.6 pounds (725g).Īs a convertible, the Yoga 900 is lighter than the 3.35-pound Dell XPS 12, 3.96-pound Asus Transformer Book TP300LA and the 3.26-pound Spectre x360. When used for long durations, the Yoga will feel heavy since you can't separate the keyboard and the screen, unlike the 2.3-pound (1.05kg) Surface Pro 4 and 3.48-pound (1.58kg) Surface Book.

At 2.84 pounds (1.29kg), the Yoga 900 feels light for an Ultrabook, but you likely wouldn't want to hold it as a tablet for too long.
