Too many topics on this... read the others

Personally I think it's a great design, looks like it could have many uses (check out the
reports on the tech demos,
official video and an
article IGN did on the possibilities of the controller/remote). The device seems like it'd be effective in most genres... the gameplay aspects may need change to change quite a lot as a result in a few genres (especially sports games) but most others it'd adapt to very well (FPS, RTS, Action/Adventure etc..). Also remember the Revolution takes standard wired and wireless GC controllers and most developers will probably include support for them... of course we have a few reluctant gamers out there so this way there's something to suit everyone.
The only thing I think Nintendo should change is add 'x' and 'y' buttons to the bottom of the remote, preferably on a rotateable axis (for the different NES and SNES button layouts) along with L+R buttons on the right hand side so the controller could handle a SNES setup and become more useful as a remote. If Nintendo added another 2 buttons and a way to attach the anologue stick device to the center left hand side of the remote the controller could also be used for N64 titles. It'd be pretty cool but Shigsy doesn't want a complicated controller with many buttons so the possibility of this happening can just go out the window...
So yeah all in all it looks like a great controller... not too keen on the apple/ipod inspiration (thank god they plan to release it in other colours), but the application and uses look really interesting. I was sold on the Reolution even before they unveiled the machine but it's good to finally have some reassurance that Nintendo won't disappoint.
