Have had a Droid X for about 5 months now, I'm extremely satisfied with my purchase.
Pros:
Android OS is fine for the most part
Screen bigger than my front lawn
Runs fast
No problems with battery life (I don't play any games other than Scrabble though and don't shoot video or anything. I dick around with my phone all day at work on GTPlanet, web browsing, texting etc.)
Lots of good free apps
Cons:
around 5% of the time, unlocking the screen causes a system reset
Android / Motorola system quirks (autoloading apps...)
Comes with bloatware (only uninstallable if you root your phone, which I did.)
Camera isn't as good as I expected
