Well, I am a bit of a tech person (besides reading a lot), so the prospect of a rooted android reader with wifi was just way too tempting... It's a great reader and a great toy.
So meanwhile, my girlfriend has laid hands on the 350 and she is not likely to loosen her grip, which I can perfectly understand. (Besides, what's the use of an unused device, it's just going to rot faster).
Honestly speaking, each time a take the 350, I think "Oh my, it's such a great little thing". Honestly, to me it's one of the very best readers around, especially with PRS+ installed (which is a firmware-addon, developed by some ingenious guys around here. It adds some functionality, which makes it really shine).
I just don't know, if exporting notes with the 350 is possible at all. I once wanted to get a drawing as a jpg and it was quite a hassle, but then, I never ever installed the Sony software, neither the old, nor the new one.
So unless someone else here can confirm that exporting notes works fine with the 350/650, stick to the T1. It IS truly a very, very good reader.
