I am not very thrilled with the slide out keyboard but the virtual one is a lot like my iPhone so I did ok on that but I feel if I put some time into the Droid's physical keyboard I'd adjust ok so just need to steal it from my wife (we swapped Voyager out).
The one thing that I can say is for a person who does NOT need Microsoft Exchange support it is working great. When we used the Droid here at work before I gave it to my wife it will sync the Corporate Calendar but will not sync email or contacts. We do not allow PoP3 connections to our exchange server so until they fix the sync issues we have to wait here at work before we can deploy these.
Now that being said, my wife loves her Droid and is checking out all kinds of cool apps and the Maps app they keep showing on the commercials really is that good. Especially since it's part of the service! I love my iPhone but the more I see what she's doing with that Droid, I'm considering switching but just have to wait until all the Exchange issues are ironed out.
