that is a more expensive 3d model-- apparently, it was recently released..(not sure if 3d would be worth the price yet..)
if you research the lilliput UM-70-- in the mp3car store, it is $165, but unlike the sales listing, it is not touch screen. mimo makes touch screen versions for about $200.
just remember-- as usb screens, they will not be recognized until AFTER the OS starts up, so they should not be used as a primary screen. but a secondary/tertiary screen use should be ok..
this is primarily because your computer will end up with a problem eventually, and you'll need to see what happened when it won't load the OS..
