There's no denying that it's a nicely designed machine, and it's pretty much what I'd expect out of Apple. Sleek, stylish, and efficient.
But as far as pure computational horsepower goes, it's squarely in the middle of the pack. It's not the slowest, and it's not the fastest. It's merely good. This wouldn't be a problem with a traditional workstation PC, where you can buy entry level, then upgrade later as you need it. But with the Pro's proprietary design and lack of upgradeable parts, it means people will have to spend more over time to keep a Mac Pro studio up to date without any real benefits for the costs.
