I mostly agree with you cybercat. Did similar amounts of research (only on the N800, not the N810; the N810 I just bought when it came out, cuz when I bought the N800 I had "just wish[ed] it has a keyboard!"). Same conclusions about Apple and PepperPad. But I didn't look at Palm nor a Journada (I specifically wanted a Unix based device).

I do think the N810 form factor could be a little better. I've posted mock-ups in another thread of what I think that should be. But, otherwise, the N810 is pretty close to my ideal (for a pocketable; as I said, I wouldn't mind an 8" diagonal device, if it had certain characteristics). Certainly closer than anything on the market thus far.
