There is one thing that bugs me everyday with the Thunderbolt. The lack of a useful LED for status information. First, It's only two colors! Second, It's useless if your charging the phone.(no way to tell if there's a message, missed call, etc.)
Even my original Droid had two different lights for charging and a 2nd status light. Why would they miss this simple design piece.
I could make a list for the Thunderbolt, but it's been done elsewhere.
December 12, 2012 is when I can upgrade my phone, and probably lose my unlimited data
