I don't have one, but am considering one. But what's *really* intriguing to me is the previous-gen refurb MacBook Pros. The nVidia chip in those is covered under a 3-year warranty beyond what you purchase (so if I read it right, you can get AppleCare and have a total of 6 years on video failures). I have bought Apple Refurb twice - an eMac 1.25GHz G4 and an Intel Mac Mini. Both have been great experience, the machines are/were eligible for AppleCare, and they're packaged and look like new.
Right now you can get a 2.4GHz MacBook Pro 15" with 200GB of storage and 2GB of RAM for $1349, $50 more than the brand new 13" MacBook aluminum 2.0GHz.
Rev1 Macs are gaining a reputation of something to avoid (mostly because Apple is put under a microscope, but at least partly because a percentage of people have issues). First-gen MacBooks mooed, first-gen iMac Intel's had failures, first-gen iMac G5's had failures, first-gen PowerMac G4's couldn't take dual-CPU upgrades, and first-gen dual-USB iBook G3's had logic board problems...so I'm trying to avoid the first-gen blues.
I do not understand what I do. For what I want to do, I do not do. But what I hate, I do.
