Guitar Hero faces JP's wrath

Guitar Hero is a gaming phenomenon...and it has seen hard rock and metal acts given more exposure, as well as earning a few extra shillings for the acts. But now Jimmy Page (along with Jack White) have slagged it off (see story here).

They make some good points, but ultimately what harm is there in it...as they point out it could spoil some learning in terms of finger shapes and rhythms, but the benefits in terms of digit dexterity could outweigh that...your views?
