For mobile computer users that want a small and lightweight system, there are really only two options: an underpowered netbook or a pricey ultraportable. Netbooks offer great battery life and portability but are usually limited to light tasks like word processing, checking e-mail, chatting online and watching standard definition video content. Meanwhile, ultraportables are pricier, but are small enough for daily travel and pack more power than netbooks. Intel's Dual Core Atom N550 is just now starting to hit the market but early reports are only showing a 20% or so increase in performance over single core Atom chips. Fortunately for consumers, other options are available, like the Lenovo ThinkPad X100e that we will be taking a look at today. Lenovo describes the X100e as something between a netbook and an ultraportable. They claim it "has the portability and price of a netbook with the power of an ultraportable."
