didn't Apple pretty much throw in the towel in this market simply by choice of form factor for their computers? The sheer desperation of their users wanting a device in this space is shown in the "creative" ways to mount their offerings in a rack.
all of the user friendly things they've done by shrinking the footprint, making them silent, etc are all things a data center does not care about. make it loud with fans to keep things cool so they can run at full load 24/7 without fear of melting down.
so from that lead alone, we can make the next assumption in that Apple doesn't care about vs CUDA. as long as they can show a chart in an over produced hype video for a new hardware announcement that has "arrows go up" as a theme, that is ALL they care about.
