I RMA'd my transformer to Newegg on Monday. Problems for me had gotten so bad that I couldn't do anything with the tablet all weekend. I was using Wakelock and Autoairplane.
It was freezing on the first Asus screen as well as the balls of death. It would lock up during use, while not in use. The most use I got out of it in a stretch was probably 30 minutes.
It should arrive back to newegg on Wednesday, then hopefully only 3 days until they send out the replacement.
I submitted a help request to Asus regarding my problems on the 2nd of May, finally on the 14th they authorized an RMA (no response from them between those dates). I had already submitted my newegg RMA, so it went back there. Hopefully the replacement will be problem free.
