... at getting a Rev. C 20" iMac? Let me explain. I bought a Rev. A the first week of November last year. I have since suffered my 4th major failure of a component (screen, mid-plane, PSU, screen, in that order

). Apple kindly told me to box it up and send it back to them. They are giving me a brand new machine. It just so happens that I dropped it off at FedEX last night.
So what do you think my odds are that I'll get the Rev. C machine?

I don't see anywhere on their site to buy a Rev. B other then refurbs. Do you think they change their inventory that fast? Do you think they keep a few thousand of the the B type for situations like mine?
I'm just curious. I'm very happy that they even considered doing this.
They are truely the finest technical company I've ever dealt with.
Thanks.
