Call me old and just want to be comfy....
I was looking at the Hero ... long hard looks ... but I'm not sold on the keyboard. Even if its comparable to an iPhone's. I have an iPod touch running their newest O/S, and the keyboard drives me crazy!! My thumbs are by no means nubs...but I have a hard time being accurate on my iPod touch...even in landscape.
Also, Google's little dust-up with Cyanogen...did not sit well with me. I know MS has sent out their share of C&D's before, but that's expected from them. When Google touts an open source approach...and then tell Cyanogen that he can't use this OR that...when those apps can be "freely" had with a search...
I've actually enjoyed the WinMo environment, albeit, it needs a HUGE upgrade (hello WinMo7 where are U??), I'm sticking with the TP2 that I upgraded to a couple of weeks ago. I was going to make a change when the Hero comes out (I'll be within the 30 day window) but the TP2 is the device the original Touch Pro should have been.
I respect everyone's opinion...and here was mine. I have to admit, however, I'd like to get the actual Sense interface on my TP2. The theme thing with MS3 and PointUI doesn't do it justice.
