I'm kind of in the same boat (I think most of us are
).
TP2 has been great. Once I settled on a ROM using Kitchen I have not touched it in 6 months !!
All I need is GPS Nav (iGuidance or similar)
Browsing
And Exchange based Email/Contacts.
Tether (Wifi hot spot is fine)
I'm concerned about exchange. A coworker has a Droid and does have it working but it's not as good as Windows Mobile (he says). I think he is very knowledgable but it's fairly stock.
Since EVO has been out for while. I thought why not wait until Sprint for next Gen EVO.
But I'm on SERO 500. And I can supposedly upgrade to SERO 1250 (still a bargain).
I'm worried that opportunity may change.
But what would I really get over TP2. Not perfect but it works. I rarely use keyboard.
With HTC's look and feel the EVO looked so much like a TP2.
Most reviews give EVO the edge over the Epic.
