The TP1 that I just had replaced (got it replaced on the last day of my 1yr warranty
)...had the rainbow on the screen. Didnt know what to call it at the time...I thought it was just something I did. Happend to look at it one day and there it was...looked like I had something on my hands and touched it accidentally. Anyway...got another TP1...about to send it back again because the thing keeps overheating. I wonder how many times they have to replace it before you get a TP2?
