Metal & Metal 2 are interesting to me. Writing those APIs while the companies that make the GPUs also write their own versions (CUDA & OpenCL) seems redundant. Unless they are planning to start building their own GPUs... which would be interesting to say the least.
Holding out for the Mac Pro?
Yes. It's going to cost as much as a car, but I'll have my column view dammit.
Unrelated side note, I'm glad there are still a few die hards out there that still come to mograph.net every now & then. I really love this place.
