If only they scaled it up 3:2 and allowed one to plug-n-play different GPGPU daughter cards. I'd love to purchase a separate daughter card that had non-FirePro GPGPU dual Processors on it to swap in and out for different needs. Or a separate daughter card to add 2 additional GPGPUs and let the OS manage their computing via OS X and activate them for OpenCL/OpenGL on the fly. That would have allowed a new definition of plug-n-play and expansion.
All storage expansion via Thunderbolt 2 for any serious performance is nauseating.
Cost just went through the roof.
It's possible that it could help push less expensive options.
It would have been nice to have an nVidia option, you need nVidia for certain tasks.
Is it possible to do SMART over any external device save for maybe eSATA?
Given that Thunderbolt is PCIe, I think it could support SMART because it would be a SATA chip on PCIe.
That said, the number of times SMART saved my bacon on any computer was zero.
