Or hang in there with your TP2 until Android gets ported over... That's what I'm doing... Been with WM for some time now and just got my girl the Hero and I'm lovin' it...
I'm eagerly awaiting the ported version of Android for the TP2... It's real close...
Check out the site:

It's being followed closely in the TP2 forum here on PPCGs:
