OK, I'll bite...
- light
This is of little of no concern for me, and I'd trade it in a heartbeat for extensibility. I don't know about you, but I don't carry my main workstation or desktop around with me much.
- compact
This is of marginal concern for me. yes, it's an accomplishment, but one I don't care much about. Again, I'd trade it in a second, for a bit more extensibility.
- calm
This one I do care about, and Apple did a great job here. Assuming, of course, by calm you mean quiet. I agree... well done, Apple!
- economical
By what measure? My math has it a heck of a lot more expensive than PC counterparts, even in the workstation class. And, as more of a prosumer, it's outrageously priced. Plus, there's the fact that it's more or less a disposable system that I'll have to ditch when its weakest link becomes a problem, vs something on the PC side that will allow me to upgrade that weak link.
- powerful
Again, by what measure? 2+ year old architecture, CPUs, GPUs, and very limited on the GPU side. I/O is also behind, especially considering that external I/O is the only path to upgrade.
Light, compact, and calm - yes, it is all of this. Calm I appreciate, but the other two don't rock my world (YMMV). These are however, great attributes for a mobile system, which explains why we now have two 12" rMBs in our family. But i don't care so much about Light and compact in a desktop or workstation.
I will bet that there are some users for whom weight and compactness are important (eg. creative pros carrying their workstations back & forth between home and office), but I'm not one of them. They are certainly "nice to have" features, but not worth the trade-off, to me. Again, YMMV.
Economical and Powerful, I would contend.
The new Mac Pro is a big success in technical terms since it is a masterpiece of engineering.
Show me a personal computer just approximately as:
- light
- compact
- calm
- economical
- powerful
And all of that at the same time !!!
Please let me know if there is such a PC anywhere out on this planet.
Now combine 4 of those 5 virtues, same question. Anyone ?
Okay, substract another one: Give me just 3 of them, three... I´m curious if you will find such a PC.
And even more, the nMP is also:
- made of highest premium quality (very stable, reliable, durable, easily repairable)
(please open the thing up and dive in, you´ll see what I mean then)
- nicely upgradeable (RAM, SSD easy, CPU a bit tricky but doable, GPU just in theory though)
I mean, this thing has a power supply inside strong enough to drive 12 Cores, 2 GPUs in any way...
If you think about those facts very carefully and compare them you will have to come to the conclusion that this PC is the best PC that was ever built, even up to today. I give a sh** on Apples self adulation but this PC is so freakin´cool it´s a pain to see people grousing about it. The only things to grouse about here are price and the non-existance of a consumer version with less pricey parts in it and the non-availability of graphic cards. Otherwise this would be the very new PC for most people on the planet and push Apple to No. 1 in PC market, too. But Apple is not aware of its value, too, obviously.
Think about it.
