Something that struck me recently while looking at a photo of Steve Jobs in his last days at his home office -- Jobs owned an iMac. The minute I looked at that I sort of realized that the Mac Pro will be doomed over the long term. I even wonder how long of a shelf life the iMac will have? Most computers that Apple is selling are portables -- and they seem to be the one company with the lease amount of sentimentality. It's going to be sad in the future when the company that commercialized the PC market with the Apple II will stop making PCs.
