I'd like to see what instructions are available on the co-processors. It seems like it would be great for physical simulations and other embarrassingly parallel things. I guess there's some need for things in between regular CPUs and expensive computing grids. Offhand, Master's and Phd. candidates might have simulations to do that this would be useful for and other platforms would be overkill/too expensive.
i'm sure it will perform effectively for more than just embarrassingly parallel problems, but a 2 gbit interconnect is a rather steep limitation. much lower than the few thousand we're used to with existing GPUs.
