I started to have some 2nd thoughts myself... still do I guess. I've been using a Blackberry 8310 for a few years now, which as my first smartphone. In a nutshell, that blackberry still beats the Droid (and iPhone) in day-to-day usability. I mean the basic stuff... keyboard usability, finding contacts & communicating with them via txt/email or voice.
That said, the Blackberry app support, browsers, speed, camera, etc... are all sub-par compared to these newer platforms.
The reason I'll stick with my Droid is because I have a sort of faith in Google that I just don't with most other companies... not Verizon, not RIM and certainly not Apple. This device has all the hardware potential I need right now... if some of the apps are kinda buggy, I can deal with that for awhile.
In my case:
a) my 2nd night of droid ownership, I was testing out wifi & got it connected to my home network. When I got up in the morning, I was annoyed to find that my alarm hadn't gone off... because the battery was toast. I assume it was due to active wifi usage of some sort... not sure
b) during a phone call, I got a message about the google phone service/app not responding & had to do a "force close"... the call was still working fine, but that command killed it.
c) the position of the buttons & sensitivity sometimes makes it difficult to juggle w/o switching modes/apps. Not as bad once you get used to it.
d) it's a tad heavy & hard to use the keyboard if you're layin' in your bed upside down
