don't mean to hijak the thread, you also might wanna consider umpc if ur preferance is to setup easy and quick but still reliable and robust... Check out this one made by Samsung called "Q1" 7in touch screen... It's somewhat powerful and has no problem running just about any frontend... Used unit runs around 500 US dollars.. blue tooth, easy mount, etc...
