PocketPC's with VGA screens - speaking as the owner of a VGA iPAQ hx4700, most PocketPC apps aren't VGA native so you won't find much software that uses the screen as it should be used (Minimo and NetFront 3.3 [still beta] being recent exceptions). Quite frankly, VGA is wasted on PocketPC devices unless you employ third-party tricks to force apps into VGA mode (tricks that I bet most non-geek owners know nothing about) and can live with the consequent side effects (tiny and unreadable text/buttons etc.)

So not only is the VGA screen not as good as 800x480, but most of the time it will be running in 320x240 pixel-doubled mode as well!
