Criticism is OK
I guess I don't like uninformed statements any more than the next guy, but I fail to understand why this board should be "supportive" of the Mac Pro. Obviously, we are all interested in the Mac Pro, but I don't want to read a bunch of fan boys any more than i want to read a bunch of haters. (OK, slightly more.) I am very interested in people's reactions, positive or negative, as long as they are factually accurate.
From a music composition perspective, I have mixed feelings about the new Mac Pro specs, but they are maybe 70 to 75 percent positive. This is by no means a push. The big deal to me is the apparent large amount of high speed connectivity accommodating SSD storage devices. That is crucial! A lot of serious computer musicians use vast sample libraries and load time is a very serious issue. The new Mac Pro, if it works as advertised, takes dead aim at that problem and that is a huge relief. Right now, a Mac Pro user has to use a PCIe slot to get the most out of SSD storage, and the competition for available slots is usually intense.
The design is largely irrelevant, although the small footprint is welcome and if the fan is really quieter, that is super important for music types.
Not so exciting: several posts above have noted that it is disappointing to see a single processor and only 12 cores. Sixteen would have been easy and 24 is certainly possible these days. I wasn't expecting a multiprocessor set up, and the Thunderbolt 2 capability raises the possibility of moving a lot of processing power off the CPU, but I have to admit it would have been exciting to see true multiprocessor support on a Mac. Similarly, the 60 GB memory limit is probably OK but it doesn't really blow you away. For most practical projects, it will be fine.
There are some design elements that suggest more improvements to come. But that's where I come up against the reality that (1) it took Apple forever to turn its attention back to the Mac Pro and (2) Apple these days is really a phone and tablet company -- computers and especially desktops are just not significant sources of revenue and profit for the company. So even if improvements are possible, you have to ask -- will they come?
As far as pricing goes, who knows? But my sense is that they will try to price these units slightly below where the comparable Mac Pros of today sit. That, to me, would be unbelievable value. I was just watching an old report on the Next Cube from 1988. That was $6,500, which is equivalent to $13,000 today (the general price level has roughly doubled since then). That thing had a 25 MHz processor, no color graphics and 256 MB of extremely slow storage. The performance-price ratio of computers has just gone off the charts in the last few decades. It will be very hard to complain about any price in the $5,000 to $7,000 range for a nicely spec'd machine.
Just my thoughts. I'm getting one for sure. And I don't even like Apple as a company - I don't have an iPhone and I think Apple stores suck -- but the Mac is a damn good product and I think the new one still will be.
