insight-free. no one has cared about RISC vs CISC for decades; they care about TCO (which includes the network effects of their preferred software stack, etc).

ARMs big problem is that it's been overpromising (to the desktop and server world) for years. ultimately, joules-per-flop is going to be the same, no matter whether the FPU is wrapped inside x86 or ARM. so the question becomes: how cheap are decent/high-end ARM chips going to be? it's not nice to be "ahead" in a race to the bottom.
