The sad thing to me is that none of them are even remotely innovative.
The NUC is just a small form factor PC, exceptionally well executed but nothing new.
Galileo is a Raspberry Pi
Edison is an Arduino (sort of)
Compute Stick is a Fire TV/Android Stick
None of these could be really considered booming markets. ARM is eating Intel's lunch in the mobile market and Intel is shooting for the products that are least likely to turn a profit. If they could get a viable x86 phone on the market (or start making ARM processors) I think they'd be in much better shape.
