Anybody heard of Guitar Hero?

Looks like a really awesome game, although I'm kinda skeptical about the game controller. They say it'll give real guitarists a headstart in the game because it's based on real guitar technique, but it seems like the feel of it would be so different than that of a guitar that it'd almost be like a completely different concept.
I've been playing it a fair bit - just about to start it up again in fact.
It's awesome fun! It really makes you feel like you're playing the songs.
I'm not a guitar player, but friends who are have the advantage that they know how to control their fingers but the disadvantage that the fret positions for notes in the song don't match actually playing it.
I bought a PS2 just for this game (well, perhaps for Shadow of the Colossus too), having played its predecessor (Guitar Freaks) on the PS1.
