I was finally able to bring my new computer home. It took CompUSA almost a week to get the data transferred from the old, dead box to the new machine. I still haven't found my old e-mail messages, but so far, I've found everything I needed.
When I picked it up, the guy said I would have to re-install all my third party software. He was wrong. Apparently, this is yet another reason Macs are superior to Windows PCs.
