I do agree about the Linux comment.  Consumer focused Linux, like Ubuntu, has consistently been about 90% of the way there to being a viable option, but has always fallen short.  I use my cell phone for both business and personal use, and I'm torn between staying with GV for the filtering capability, but the lacking of MMS is a severe blow.  I made the mistake of porting my phone number from Verizon, so now everyone calls me at GV.
