I recently did a refresh, and reinstalled all my apps. Besides recovering a ton of memory, another benefit seems my GPS has improved a lot. Not great, but certainly better. But now the battery dies REALLY fast. the only thing I've done differently is heavily modify my screen setting using ADW launcher and beautiful widgets. When I check battery usage, it just shows "Cell Standby" and Phone Idle". I can't imagine this making a big difference on my power consumption. Anybody notice a battery drop when using these APPS?
