I ordered mine first thing Monday when the store had the new machines. (BTO 4-core, 3.20 GHz, 8GB ram, plus Aperture 3) FedEx makes it look like my machine missed the first flight to Alaska and is now waiting in Hong Kong to ship out. Delivery NLT Aug 24th, though I'm hoping I get a delivery notice on Monday. I've been waiting a year for a new machine, and it should last me about six, so three extra days won't kill me.
That being said, how does pre-installed software work? I assumed they just send me a box along with the computer, much like the mini-DVI to DVI plug I ordered. I can't imagine they have tons of different "restore" DVDs with different pre-installed software. I hope the pre-install isn't what delayed my machine! Still could have gotten a student discount just ordering it separately.
