I'm not sure why everyone seems to be wanting an IR remote in our hopes with the Front Row potential.
Has anyone here ever used Griffin's Airclick? It's a little remote control with USB reciever and it's all RF (radio frequency) so it goes through walls, other rooms, etc. And it works very, very well.
So my hopes would be a remote that looks very much like the current one, but where the little "shuffle" style navigation is, you have either a touch track circle, or a multidirectional nav button (to control your mouse pointer, etc.) and whatever buttons or style of controls would be most beneficial,... but my main point is not IR, but RF. It's much better range, and battery is way better than bluetooth. So yeah. Even if it's a USB receiver, or just built inside like an airport.
That's what I think would be far more useable.
