From the Review:
Editor's Choice
The Lenovo ThinkPad X41 Tablet wins the Editor's Choice award for being the most comfortable to use and also for having excellent communication offerings from gigabit Ethernet, Bluetooth, and Wireless a, b, and g support. Its super light for a Convertible and the build quality is second to none.
It's down on processing power compared to the rest of the field but it's no slouch.
