Honestly, I still don't understand why an entire day isn't long enough for most people. Here's a simple idea: put a charger by your bed. I have a chord draped over my nightstand, and when I get into bed, I plug in my phone. It's pretty darn easy. My phone hasn't run out of juice since I got it in October. Between my car charger, a USB data cable, and that home charger, I don't see any way I could run out of power.

Also, I had the Treo 750w, and never thought the battery was a problem. Then again, I seem to be the only person on the planet who liked that phone...
