It's really annoying to have a really powerful Mac Pro bottlenecked when you press "open with..." on something and have to wait for an external hard drive to wake up while Finder hangs.
Edit: I know that you can disable hard drive sleep but don't want to have them always awake, and I have already excluded them from Spotlight search.
You don't want them to always be awake but you hate to wait for them to wake up. Seriously?

Hmm... And I just finished building my render machine with 2x 2687w xeons (16 cores) with 64gbs of ram and a GTX Titan.
I feel like I should have waited a few months?
If the user interface and operating system mean anything to you...yes.

Why are Mac fans excited about the performance of a Windows system?
Especially when they know that there will be Windows systems with two of these chips - but Apples will have only one....
I'd love to see benchmarks of 24 cores versus 12 cores before I care about this.
Also, I'll care about this when my pro apps switch back to relying on the CPU versus the GPU.
----------
How were they able to run benchmarks on a computer that hasn't been released? Secondly, Mavericks is still in Beta, I would never rely on Beta benchmarks on hardware that wasn't released. Not to be weird, but I would wait until the final release.
Based on the past, the final OS X doesn't perform any differently than the beta.

I am excited that the chip shows some sizable improvement over the Westmere...I am not excited about the "new" Mac Pro being a single-processor machine with no other options presented by Apple. Dual Processor power is one thing that made the high end Mac Pro so great....for power users that could afford it, you got a helluva machine. Now Apple appears to be offering us no more than a souped up headless iMac with a Xeon processor and a tricked out custom graphics card set, that appears to be soldered onto the board.
The fact of zero internal expandability has me a bit perturbed about the thing...it's a MiniPro, not a Mac Pro. This is a power mini with better parts than a Mac Mini...a true Pro would have better internal expandability options and not require 20 cables coming out of the thing to get PCIe and hard disks.
With your logic, having 4 single-core processors is better than 1 12-core processor. Of course, that's ridiculous.

The current Mac Pro can have 4 internal hard drives and 2 internal optical drives. The new Mac Pro has 1 SSD hard drive. Soooo, that means you would have 5 cables, not 20.

People still miss the forest for the trees: the Mac Pro is designed for the future, not the past, and gets much of its performance from the extra GPU. Luckily, I'm buying for the future too!
And that SSD!
I don't believe you're required to allow drives to sleep. And I don't think Thunderbolt makes drives sleep in some way that is different from internal bays.
P.S. It's fun to see people who would never buy 24 cores complain to other people who would never buy 24 cores that they wish they could buy 24 cores. "Bullet list marketing" at its finest

Catchy specs over results? No mention of OpenCL, even from people who like to brag about performance numbers?
Duel GPU is not the future. Windows PCs have been doing that for a decade, at least.
It's just an extra cost running Macs. Mac users should have been able to do SLI years and years ago but couldn't. Now they can't use all those PCI slots in their Mac Pros to have multiple GPU making GPU-intensive apps like Apple's Final Cut Pro X and Motion faster, they have to buy a non-expandable new Mac to do it.
I'm really on the fence, now. I'm giving Apple one more shot at making FCP X good enough for me. I've had it for a year and it really is garbage in many areas. If I switch to Adobe Premiere Pro, I'll get a custom Windows system. I don't see the point of running the Adobe Suite on a new Mac Pro, assuming the cost of it is similar to existing Mac Pros.

With GCN 2.0 imminent the HSA 3.0 standard and OpenCL 1.2 built throughout OS X 10.9 those FirePro cards will scream.
By the way, Apple approached Blender to help them port Cycles Rendering to be fully OpenCL 1.2 compliant for the Mac Pro, when they met at SIGGRAPH 2013 July.
Proof is in the pudding. It's not that way right now. "Just you wait!" has been a rallying cry for the Mac fan a very long time now.
FCP X can't even scroll its timeline while playing a project, so please don't argue that it screams with OpenCL versus Adobe and CUDA.
