I sent mine in to have the cracks repaired. The rep told me I'd get my original back. 10 days later I received the return, but it was in fact a DIFFERENT touchpad than what I had sent in. They included a paper statement that read something along the lines of they could not repair it for one of many possible reasons. Not only that, but the F'ing thing wouldn't even charge or power on!
After a quick troubleshooting session online they are sending me ANOTHER return box/label. Hopefully in 10 days I will have better news.
...For the record, I'm betting they send me a 16gb by mistake, instead of a 32gb. You heard it here first.
