One of the other "cool" new features with the 27" iMac I read, is that with a third party cable (coming out soon), you can actually use the 27" iMac as a monitor on another machine (as long as it has miniDisplayPort). Can see that as being useful in some instances.
But yes, the new top of the range i7 sounds like it's going to be quite a good machine. And well priced! Especially for Quad cores!! :o) And now with it being larger it has 4 RAM Slots as well (up from 2), as it's "longer base". I also read with the larger size the sound quality is improved as well, as they've had more room to work with the speaker system (or placement) of it to get better sound. (Side note to Martin. Should I guess you'd be loving one of these to replace your "eyeTVMac") ;o) hehe. All round looks like a nice upgrade I think.
