Well I became a Droid owner back on November 3rd. The same day my company sent me to Utah to open some new locations. Fortunately unlike California (home) the VZW stores are only required to charge tax on the paid amount of the phone, not the full retail price. So I made sure to buy it out there.
I bought the Droid because I despise AT&T, and I don't like supporting Apple and their insistence on locking down every single thing they make to the point that basic customization is restricted.
I formerly had a Moto Razr, Samsung (idk...), LG 8550 (Chocolate 2), and then the Droid. Been into modifying phones ever since my first one - using Bitpim, and reading a lot.
Its nice to have this massive community already dedicated to making the most of these great smartphones. Not just that but the entire Android community in general. I'm already rooted, busyboxed, custom notification bar, bootanimation, and I'm working on a few other things.
p.s - Thanks to Google for such a great system, and for not being as proprietary as the Cupertino's...
