I'm really excited about the new Sony Readers. I recently bought a nook to replace my aging 505. I like the nook--but one of the main reasons I bought it was for its dictionary feature---which on the nook is less than stellar.
The new Sonys with two english and multiple translation dictionaries are very attractive.
My husband has a Sony 900, and I really like the touch screen interface too. If the screens on the new Sonys are as clear as they are purported to be, I may have to find a way to justify purchasing another reader after only owning my nook two months.
And I don't find the no Wifi, no SD card slots, and no headphone jacks to be negatives. I don't use any of those features on the readers I have. I might go for the 350 just to have a device with a smaller form factor.
