I need a new phone! ASAP - need recommendations...

Last night I played Angry Birds for the first time - on my friend's amazing Samsung Galaxy (thx Jamel) and since then my life hasn't been the same. I now see what my app-less life is and it sucks. Angry Birds was so cool - and also addicting, that today Mashable posted that its coming out on other platforms - aka real gaming platforms - who would've imagined that.

Should I wait for a Windows Phone 7 on Sprint - or should I just jump on an Android...
