I upgraded from the OG Droid, and so far I am very happy. The phone is extremely crisp and snappy with no noticeable lag. Swype comes pre-loaded which I think is a huge bonus (I know I could get it otherwise, but no hassle this way). While there is bloatware, much of it can be uninstalled, and anything that cannot be uninstalled is easily 'hidden' from the app drawer. As advertised, the phone is very light and thin. I admit, I thought this was a gimmick, but even with the larger screen, it fits better in my pocket and fits better in my hand. I can't fully comment on the battery life yet (purchased yesterday), but so far today with moderate use I am still at 70%.
My advice to anyone is check the phone out, and if it suits you, go for it. We can all forever wait for the next best device, and never upgrade. If a phone suits your needs, why continue waiting? The OG Droid was a solid device that made it two years, and I have no doubt the Razr will do the same.
