Well, I have been playing with the droid for a week now and have made the sad decision to return it and go back to my Windows 6.1 phone ....
My primary reasons for returning it are because I am a serious road warrior with my phone and it is a critical business tool.
My Droid fails as a business tool in a couple areas (where my Samsung i760 does great)
1-teathering, got it to work but it is slow and a bit of a pain
2-Exchange outlook, email synces great, but the mail client is lacking functionality (accept invites, sort, folders, etc)
3- calander (corporate) very lacking in functionality
4- call signal strength, I loose calls easily, and people complain of poor voice quality on their end
5- lack of edit capability on docs, xls, other office stuff (some apps available for a price though)
6-very hard to use while driving as everything takes multiple taps, slides, or other visual type things to do. Not good in a state where cell phone usage has strict limitations
7-keyboard is a bit hard to use compared the great keyboard on the 760 (I could get used to it, and the landscape onscreen keyboard is actually very good)
8-Bluetooth functionality is very poor. No handsfree dial, voice command.
I think the phone is great for a casual user and the form factor is nice and it feels solid.
I know there are OS updates due out in mid Dec, and again in Jan. that will (may) address some of this, but since I only have a 30 day window to decide if I want to keep it, I have decided to stay with my bulky but tried and true i760 and re-evaluate the droid once the new OS patch is released.
Not trying to rain on any parades, just wanted to give my feedback to those who are looking for a business phone and are not able to compromise on the core phone and PIM functions we are accustomed to.
