I have one, but now I'm thinking it was most unwise to buy one when the HTC Passion is likely to come out next month. Faster processor (1 GHz to Droid's 600 MHz), bigger screen relative to Droid (4.3 to 3.7), great user interface, and runs Android 2.1 (I think). There's a great chance it goes to Verizon, but really that's up in the air.
All in all, I like Droid. It's a bit more complicated to navigate than iPhone and not quite as intuitive as iPhone, but the call quality is excellent and the display is fantastic (has a better resolution than iPhone). It also has free Google Maps navigation. I think it can lose the QWERTY keyboard, as it's a bit clunky. It's not as good as iPhone with regards to playing music/video and so, if you're looking for a smartphone with all the multimedia bells and whistles, Droid doesn't quite fit that bill yet. Another downside is that the number of Android applications are limited relative to iPhone, but the good news is if Android takes off as a platform, more developers will flock toward making apps for it and they likely will, as it's open source. Apple being Apple, they have sole control over what applications are sold on their AppStore and a good share of developers aren't too happy developing for iPhone. If Google/Motorola can fix that design bug about applications only stored on internal memory (it's only 512 MB) and onto the SD card, that would be massive.
If I were you, I'd probably wait for when the HTC Passion comes out. I will say that aside from the processor being superior to Droid and the camera's capability to record 720p HD video, Passion is just a souped-up version of Droid minus the QWERTY keyboard. If it has that hardware design fix about storage, it becomes a much bigger upgrade than Droid, IMO.
