Handy

Very convienient to have and got to love that magnifying glass feature. Super easy to setup, takes 2 mins. Only downsides are slight lag occasionally, the landscape keyboard is really low quality, no volume control, and no good scroll feature. But for what you pay its great and very useful.
EDIT: Works great with XP but Windows 7 it changes the icons so that when you click on them it opens up properties for that icon/program.
