Sorry I didn't respond to this sooner, but it looks like I had a similar problem. In my case I was getting random touches on the left center edge of the screen. I got it solved by sending it back and getting a replacement. But that wasn't done very easily. I bought it at the Microsoft store and they sent it back to Sony, and make a long story short it took about five weeks before I got mine back. And it is the slightly newer model with the faster processor. I sure hope my new one doesn't go do this again. Five weeks is just too long. If it had not been for my personal use but for business it would really have been a problem. Oddly enough I used it as my software development machine at work for a few weeks, and just before it died I got a nice i7 desktop from Lenovo at work. That really scares me. In a business environment you really need to have an immediate replacement when a machine breaks down.
