I don't own one yet, but I ordered an n810 earlier today, and it should arrive soon. The reason I did was that a friend from college and his wife visited over the weekend. My friend's wife had an n810 and let me look at it for half an hour or so. I was previously torn between an ipod Touch and an n810, and had almost decided to get an ipod Touch after playing with it in an Apple store.

However, the screen on the n810 was incredible, that alone made the n810 a truly amazing ebook reader, and I love both the browser and the keyboard. All the reports I've heard about the n810 keyboard being difficult to use were clearly made by people with fingers very different from my own. It made the keyboard on my aging Sony Clie look like a piece of ill-made junk. Also, simply the fact that the keyboard was so much easier to use than that screen keyboard on the ipod Touch made the decision for me, the rest was gravy.

Of course, I know nothing about Linux of any flavor, but with luck I'll learn fairly easily.
