It's actually the inability to swap out innards that enables it to be so powerful, and at such a reasonable price. That's the limitation of a "System on a Chip" design.Another extremely enlightening thread. I thank you all for your input.
I’ve been waiting for the smaller variant of the Mac Pro, but it sounds as if the Studio does a superb job, short of being able to swap out (I’ll use a high tech term here) the innards.
I almost hate to admit that I had no idea this area of the forum existed.
It's a great computer, and plenty for anyone short of the most demanding video production.
