I've recently bought an n810, my girlfriend bought an n800.

We both had different priorities for the tablet. She wanted to use it primarily for multimedia and maybe for pim purposes, so the extra space was a pro, and the fact that it didn't have an keyboard or gps didn't bother her.
My foces was hacking, ssh, nethack, a bit of pim, and finally some multimedia. Therefor I like the fact that s has a keyboard, the fact that is has less space does not bother me, and the internal gps is a nice extra. I don't have any other gps system, and from what I've seen, the gps will do just fine for what I have in mind.

I like keyboard of the N810. Although when I need to type little things I use the onscreen one, when I need to type more (or play nethack, in the console offcourse), I use the keyboard. I do think that if they would move the d-pad and the other controll button off the keyboard thus creating extra space, to be used between the keys, it could be even better.

But I like it, very much even. But it does need a little tweaking .

ps.
I've compiled Linley's crawl for the N810, it requires almost no changes to the code to compile, just some makefile tweaking. Offcourse this is just the console version. It also needs the scrollbar of xterm removed, but it works great. I'll try to optimize the output for the N8x0 some more, if people are interrested.
