If it's any contribution to this loopy choice-justifying discussion (which is really very helpful for those interested in buying one, as I have recently learned), I eventually decided the N810's keyboard wasn't worth it to me because I do fine with writing recognition. I have come to actually enjoy using CellWriter along with my Wacom tablet, and I understand that program could work pretty happily on Maemo. Other peoples' mileage may vary, but my writing, while messy, is quite consistent.

For that matter, one of my software development goals is to eradicate the use of keyboards wherever they are not necessary for hand held devices, in favour of either more natural input -> text conversions or skipping text-only content altogether. (Everything being text-only makes sense in some cases, but it is unnecessary for a surprising number of things).

Thus, I can do fine with neither an on screen keyboard nor a physical one!

Also, I realized size isn't an issue when I discovered they are both similar in size to my Iomega 120GB external 2.5" hard drive. (Which is tiny and pocket friendly). In fact, the N810 is identical in size, but the 800 is just a tad wider and taller by millimeters. Both are, by that compass, sufficiently tiny.
