I am one of the ones having crashes, but I haven't seen any other reports of people having problems like I'm having. I think I just got a bad unit. I love the device itself and feel sure that these problems will not be present after I exchange it for another unit.
(And the the point that people only post about their problems: That's probably true in my case. I don't think I ever posted to say how easy and trouble-free my Sony PRS-T1 has been. It runs like a diesel, but without the smell!)
I found my Glo by going to the American Booksellers Association web site and locating a member store in my area. I checked that store's site (Park Road Books in Charlotte, NC) and called to confirm they had the device in stock.
