Have been following the thread for some time, did not want to go for replacement cause happy with 6800. Powr jack broke today, went to repair center, they say ithere's water damage and nothing they can do although power socket has nothing to do with water. Called insurance. They had 6800 in stock, I asked for T Pro, talked to another person, they agreed as courtesy. I guess if I am going through trouble of getting to repair center, hten being rejected of service on wrong basis, then for my $50 I am entitled to something more than simply 1 to 1 exchange.
