The new Front Row interface on the iMacs looks nice. I wouldn't buy a new iMac to get it, but as an added benefit it's a nice one. I'm wondering: is it simply software? i.e. is FrontRow an application? If so, can owners of other Macs (such as PMs, eMacs, 1.8GHz and prior iMacs) use it? or does it require new iMac hardware? Obviously you won't be able to use it with a remote unless you have the new iMac, but I wonder if you can use it with your keyboard or mouse on any Mac. Anyone know?
