I got an N800 for christmas for myself and put sudoku on it so my wife would like it too and I can justify the cost somehow . Now she barely puts it down.
She stays at home with our 2 yr old and the Nokia is very usable. She can browse craigslist all day and check email, bank account etc. ... we use it to call relatives via skype in europe. Its great!
And having no kb is great when having little touch-everything-monsters at home. Just don't show them that there are little videos inside! ( Now he brushes his teeth while watching BluesClues in bed.)
