I disagree with that view...
To me the main reason for the Natami is quite simple, I'd like to be able to buy a new Amiga that can run all my old software, hopefully a bit faster on things like PageStream & ImageFX, without having to scour ebay and pay ridiculous prices for an 060 board.
The ability to access the net would be nice but not a necessity... 
If thats all you want then uae on aros on a PC is probably good enough.
