I forgot to say, I asked the Sony guy if it was running on Android and he said in an evasive manner (without making eye contact), "Oh, I don't know anything about the technical stuff!" I said, "Well I notice it has a back button now, just like Android." He said, "Oh we just thought that a back button made things easier for our customers. Now you don't have to use the home button and start again, you can just press back." Then he demonstrated it for me.
He look decidedly uncomfortable the minute I mentioned Android.
