I just returned my PRS-T1 to the retailer
I had already done this once after the freezing/dictionary issue, just in case it was the unit itself. Got a new one, and the same thing started again. As an insomniac who reads in the middle of the night to get back to sleep, I just couldn't handle fast forwarding through 400 pages and then being frozen out for 15-20 minutes at 3 a.m. I waited until Nov 30 for the update and then called Sony. Once I convinced the call centre that it was actually a recognized issue I was told it would be Dec. 2, at which point it became mid December. I then decided that I better return the unit before the retailer's 30 day return policy was up.
I'm really missing my ereader, but so far my paper book hasn't gone crazy, and I'm always able to change the pages when needed. As soon as this forum indicates there is a functional fix I will head out and buy another. Hoping it happens really soon ...
