I'm interested in this thread as well... In my research i'm favoring the Sony Daily Edition (PRS900BC) at this moment over all others.

I'm not interested in the wireless capabilities but everything else i've read about (including the negitives) seems to be ok for me.

If Amazon offer a Kindle model without the keyboard (software version is fine), have a slot for SD cards and open it up for more document formats; they would have a much better product. Well, a product that I would purchase.

That Sony model does have a few issues (boot up is slow at times, etc), but does offer a better package IMHO.

But thats my opinion at this time and i'm sure others will chime in with their experiences/research. I maybe persuaded to change my mind!
