Got one for my Wife.
I am amazed at how easy she got her email set up, and was very happy to do so. The phone is very well set up for ease of use and this is the best feature of the phone to me, because my Wife is using it just fine.
It will be easier to list the things I don't like, but I assume they will be fixed as this phone is mostly Software OS issues for me.
1. The apps are unorganized and it is difficult for my Wife to find things. Old Palm had categories.
2. The Touchstone turning the phone into a clock is cool, but I want the option to turn the screen off.
3. Contacts need some more tweaking, maybe categories for them as well. They can be a bit confusing what with Facebook etc.
4. Need more syncing options with Hotmail/IM.
5. Something like voice command would be very nice for contact name calling with a headset. Otherwise I can only see speeddial as an option.
6. KB is nice enough, but I think they should have done it wide like the TP, for a better layout. I can get over this one, but I still believe a stronger KB would have been keen.
7. I myself cannot stand the banner advertising on AccuWeather, and I don't look forward to the future of that if that is a preview of what is to come. I am also surprised that weather was not a stock program on the phone.
All I can remember for now, and all to me seem to be trivial software tweaks. I think we can all look forward to this phone growing with the app store and OS updates, and good lord if it goes open source!
