Fujitsu has revealed two of the world's lightest 13-inch laptops at a launch event in Japan. The UH75/B1 weighs a scant 1.72 lbs while the U937/P weighs 1.87 lbs. The base units come with a small 25 Wh battery to reduce weight, but a 50 Wh battery is available, which will make the laptops weigh just over 2 lbs.

Wow, nice beefy Enter key and normally spaced and sized arrow keys! Fujitsu really is the last good laptop maker.
