Well what is the N900 then ? I think adding a sim card slot is a great idea. If you don't need it then don't use it, but it cuts down the amount of gadgets that you have to carry around and it makes sure that you are connected wherever you are unlike 770 which would be useless in an area with no WiFi.

So if I have to pick between any other tablet and N900 then it would be the N900 hands down. As for pricing then all I could say is "this is Nokia", the Booklet 3G sells for $600 compared to $200 ~ $499 netbook range so Nokia is expensive in general.

So if I have the option to have a tablet with 3G SIM and telephony available for $100 more the so be it.
