I almost fell off my chair laughing, Thanks for the laugh.
Do you really expect something like what your describing to be able to do anything remotely intensive?
My workstation almost chokes on what I do for a living, and it has 4 Quadros, 128gb of ram,( very recently upgraded thank god, more than one project at a time now

) dual over clocked xeons, and 10 hard drives. With a boot SSD Drive . How in the name of god is a Mac Book air with a PCIE 4x expansion slots with cables attached going to come CLOSE to what a high end work station can do?
To give you an idea, this is SORTA what my workstation I use at work is. Mine is more of a totally Custom build, but this is the closest thing you can buy today. And have shipped in a few days. The main differences is that I have 128gb of ram, better processors, ( OCed Xeons ). And Quadros instead of gaming cards.

Think of it as kind of a mixture of those two ( I think I might have the same case as the second link I posted. )
But you get the general idea right? How in the hell is a MacBook Air with some choked external TB devices gonna come slightly close to what a machine like that can do? Apple should be building machines more than that, the profit margin is pretty huge on something like that.
Now GamePC is just one of MANY high end PC vendors, HP, Dell, BOXX, RainPC, and just to damn many to list. Look around the GamePC site just as an example.
Apple doesn't offer any computers with anything like the capability of those machines, and they need to. Which is what a lot of Mac Pro users wanted. And didn't get. That's why people are pissed. I'm pissed myself for not being able to get a good Mac Workstation for some fun at home.
Apple saying " yeah we updated it ermmmm kinda? MAYBE in a year and a half or something you'll get a new one...maybe "
Sorry Apple, but as much as that kind of money for a new MP isn't so much an object for me. I won't be spending my hard earned cash on a two year old Workstation that isn't worthy of being called a workstation. At least not anymore.
Cmon Apple, what the hell happened to the constant Power Mac G5, G4 and G3 updates? When you actually kept pace with PC hardware? You actually supported your most loyal customers? What the hell happened to Apple being considered a serious computer company that offered some very serious machines.
I still remember buying my Dual 2.7 G5. I was excited, at the time it was probably one of the best made and one of, if not the fastest desktop you could buy for anything under 10 grand. I loved and still love mine. Sad to say, I don't think I'll ever get excited over another Apple.
Half assed update 2 years later....maybe we'll think about building another one....uhhh...buy an iMac? iPhone? ITS SHINY - Thats how I see apple right now.
Its to little. To late.
And I REALLY don't want to hear " Oh that machine is total overkill! A Mac Pro is already plenty fast for most people who really need a workstation!!!!! "
WRONG.
