Two things make me expect disappointment:
- Mac mini pricing (with decent amounts of RAM and storage) is absurd, and there's no way the new Mac Pro will be more affordable.
- The fact that it's taking them this damn long guarantees that we'll get an over engineered, over complicated, and over priced machine. It doesn't take years to design an expandable chassis.
I've been using Apple products since my family got an Apple ][+ when I was a kid. I've used Windows machines in various jobs, but I've never once purchased a non-Apple computer. I hope never to have to, but Apple pisses me off lately.
Apple is becoming a victim of their own success. Johny Ive and crew have produced some beautiful designs, from Macs to iPods to iPhones. But now it's design and flash über alles, practicality be damned.
I used to be able to say, "Apple doesn't sell low end computers, but what they do sell is price competitive with comparably equipped PCs." Take a look at the Mac mini, and you'll see that's not true anymore: In many ways (particularly GPU), it's a low-end machine at high-end prices. Granted, the Mac Pro will be a high-end machine (at launch anyway; we'll see if Apple leaves it to languish again), but I expect the prices will start out high and quickly rise to ridiculous once options are added.
Apple, just give us a box we can open easily, that we can add RAM and storage (both SSD and HD) ourselves, with an upgradeable GPU. You did this a decade ago, and every other PC maker does this today. You can differentiate yourself from the others by making the box not ugly, and of course, with Mac OS. It's not that complicated, so stop making it so.
