"Mac Pro, now diminishing productivity even better!". Seriously, using Apple stuff for productivity is like hammering screws and screwing nails...
So very wrong. You're ready to throw Apple's hardware (and possibly also software?) under a bus, yet you give no reason why, outside of a bone-headed comparison to carpentry...
Set aside the inherent benefits of administrative simplicity and security of OS X (yeah, you'll never convince me that the 'doze registry is somehow less-complicated than a UNIX-style file hierarchy), the legions of advertising/production businesses/artists that rely on Mac-only software, and the general aesthetic quality of Mac hardware...Now tell me, what is it about this new Mac Pro you find so ridiculous?
Think it looks silly? Maybe it hasn't occurred to you that the cylindrical design nearly eliminates airflow/heat issues that have always plagued the boxy PC case? Or, that the decision to divorce the internal components from the obligatory 90 degree angle connections to the motherboard (used in nearly all computers for years) allows for improved cooling and a seriously-shrunken form factor? I CHALLENGE you to try to fit 2 video cards and this much processing power/storage into a PC with smaller dimensions and better cooling...even if you can imagine something and put it on paper, you won't be able to go out and just buy the parts for it. Someone is going to need to specially manufacture what you need.
The fact is that Apple is one of the few players with the wallet, connections, and innovative thinking to make it happen. Sure, someone else could've done it first, but they didn't. Doing something different doesn't always turn out for the best, but Apple has done something remarkable here, win or lose. Incidentally, this isn't the first time for the company; they did the same thing for the mobile phone some time ago. Oh, and also to the PC years earlier.
Granted, Tom's is a community of enthusiasts, and a lot of us enjoy crafting computers ourselves rather than paying (admittedly) grand amounts of money for pre-assembled machines. That doesn't mean this new Mac Pro a POS, or that its design is any less impressive.
In short, if you consider yourself a real enthusiast, understand the fact that different systems excel in different areas. Just because you prefer one system for all of your tasks does not mean that it's the best system for each one of them.
