Some of the problems are still there (the missing dictionaries for once, no book search), but they are going to introduce them (they have made like 3 fw update in 2 weeks I think), some there are not: the browsing is there and it is fast, the pdf scrolls smoother than other readers because of the HSIS, the USB issues went away with the first firmware update, and the device is the most customizable of all: you can use your own true type fonts with it!
On the other hand, it has it's problems of course, and the sony has a very nice white screen - Odyssey is a very little bit grayer I'm told - plus it's android.
In fact, Sony has lowered its price to 159 like the Odyssey in Italy, and I was really tempted, the only thing holding me back is the lack of hw page turn buttons...
It still is a close decision but ultimately it won't be taken by me. :P I can only wait.
