On the other hand it's nearly impossible to use, with a too small optical track pad and a too high pixel density -- combined they make hunting down just about everything in the OS a painful affair. - Paul Miller, Engadget http://www.engadget.com/2009/09/03/sharp-pc-z1-netwalker-hands-on-ubuntu-like-youve-never-seen-it/

The NetWalker is dressed up like a super-petite Netbook, weighing less than a pound, with a five-inch touchscreen and a measly 512MB of memory and wireless LAN. - Erica Ogg, CNET http://news.cnet.com/8301-31021_3-10368341-260.html?tag=mncol

Sharp, maybe you should make some coffee. It has become pretty evident in the last few years that devices like this have failed more times than not, especially for an above $400 price point.
