debernardis,

It sounds like we're basically in agreement: it depends on what you want to use the tablet for. Nobody would claim that the N800 is a universal solution. You may be right that somebody will produce a kind of mini-Office for the internet tablet. I'm sceptical of claims of round-tripping. Over the years, I've tried various apps that claimed to be able to read and save Word docs, most recently Nisus Writer Express on the Mac. As far as I can see, they tend to work best when the formatting is trivial. Footnotes, tables with cells that span either rows or columns and, oddly enough, cross references usually produce unsatisfactory results. I haven't actually tried a doc with a table of contents or an index but I wouldn't be optimistic.
