I actually changed my mind, partly (but not exclusively) because of all the reports on the t1 freezing and crashing. Besides, my male intuition just told me to go for the coolest and most beautiful device
So, a used 950 in excellent condition is now on its way to me! Really looking forward to it.
Concerning the t1: I realize that it has features that the 950 doesn't have. But I think I'll pass on it this time, and wait till the t-2 (or something) arrives. By then sony will have had the time to fix everything that's not optimal on this one. Then I'll have two devices: The 950 for couch reading (I think it will still be excellent for that), and a more portable one for travelling etc
