thanks again for the info!

yeah I guess maybe for PI it will work well since it supports VGA

as far as the touchflo is concerned it's not the same like you mentioned

there are three versions of touchflo I know of:
the first one is the original one that came with the HTC Touch (my current phone), you slide your finger across the screen from bottom to top and it brings up a touchflo menu on which you can slide your finger across the screen from left to right or right to left to flip the mneu around...it's really just a cool feature, not quite useful

the second version is what you mention in which you slide your finger across the screen to activate various programs but the benefit you have is that your version is customizable (unlike the original one that came with the HTC touch) so your's can be much more useful

the third version is the one that comes with this HTC advantage. It's not like the first two at all, this one simply let's you "tilt" the device up or down and it will scroll down a webpage for you....it has an accelerometer like the iphone basically....this technology is actually called vueflo

the ultimate would be to get the htc advantage and have the vueflo...but also download the touchflo software you mentioned for the ultimate in customizability

im trying to find a good price for the htc advantage, it retails for $900 and I saw some brand new ones end on ebay for as low as $600 shipped

right now however none are going below $700
