I'm going Evo from an LG Dare, so every second is torture till the 4th. I was waiting for my contract to be up, and wanted a Droid, then decided to wait on the Incredible, then realized I was willing to change to sprint for the bigger/better Evo so I'm still waiting even though my contract was up in March.
If you've got a decent phone, then the rush isn't so important. There are drawbacks to being an early adopter (no 4g in beantown yet), though I doubt there will be a rev2 evo any time soon.
