Apple has stated that it intends the iPod Touch to be a mobile internet platform so it does in fact compete with the Nokia N 800/810. It may not currently have the expandability of the N800/810 terms of software but when the dev kit arrives it will and at that point it may well come to rival the N800/810 the question I have is whether Gnuite would port Maemomapper to the IPhone (assuming some GPS over bluetooth is feasble there) since that is the only app currently that would tie me to the N800/810.
