At 10x10cm, the NUC is actually one of the smallest complete PCs on the market. The only x86 competition comes from VIA, which has produced Nano-ITX (12cm), Pico-ITX (10cm), and Mobile-ITX (6cm) motherboards for a few years — but these motherboards only support slow, weak VIA CPUs, and are generally targeted at embedded, low-power installations. That Intel has managed to cram a mobile Core i5 processor into such a form factor is rather impressive.
My prediction - next amateur cinema cameras won't be produced by giants only. But 90% of them will be using common interfaces and common CPU architectures (x86 and ARM).
