the pre is an awesome phone. multi-tasking, wi fi, keyboard, and my favorite is that you can use it with one hand.
but now for the bad. the app store is good, but it is not up to par with the iphone, or especially the android market.
if you dont need a lot of specialty apps...go for the pre.
if you do need lots of difficult to find apps, go for the android, it has the most free apps, lots of apps that cost you money with the iphone are free with the android.
