I have had the ThunderBolt and kept it for 5 weeks and got tired of poor battery life, lock ups, reboots required to get it from being locked up etc. I tried the Revolution but I had dead pixels and honestly that hasn't happened since the early part of 2000 on WinMo phones, it went back. I have the Droid Charge, and SAMOLED+ displays are simply awesome, but the lack of internal storage is a limiting factor for me. I have nearly everything on my SDcard and that is a PITA.
I am leaning heavily towards the D3, and it was driven home today by one simple thing. I was actually out shopping and wanted to check something online while I was at the store. Using any smartphone with an onscreen keyboard in a PITA, it takes up 90% of the display to type, then the autocorrect comes up, you can't see what your typing it was more aggravation that it was worth. I realized if I had a physical keyboard I could actually type with the full display at my disposal, something I haven't had in a long time and something that for me is worth it.
Now I will get a 4G LTE phone, but I am willing to wait until next spring/summer when the ICS phones that are all display, no physical or capacitive buttons and are truly worth getting. When we get phones with Quad cores, 720p displays and battery life that can actually be worthwhile then its worth getting 4G LTE. If you can't get through the day due to phone lockups, and dead batteries then its not worth upgrading, yet.
So I guess my answer is yes, I will be calling in once its announced to place my order.
