I have a N810.

Use it daily for several hours: browsing, email, ebook (pdf), MP3. Notebook substitute (with BT keyboard) when travelling. It is still more in use than my real computer.

Like to see the community SSU update. Would like TEAR to be a full alternative to the standard browser, but it seems development has ceased there too.

If my N810 got stolen/lost/broken, I don't know how what to buy then. It would not be a N900, for sure.
