I did do the research. PAN/DUN issue is not something you come across. and I was told that Abiword and Gnumeric can replace Word and Excel, but they are not even close YET. If browse-on-the-go is the only feature thats advertised, N810 certainly does that well, but $400-500 is a little to much for just that feature IMO. OQO2 is a much better device of course, but it's not in the same price range.
