 it's more that they're on a losing battle in the all-important
"price-performance-watt" metric due to the extra overhead associated
with x86 instruction decoding compared to RISC (that 500mhz dual-core
Cortex A9 video produced by ARM comparing to a single-core 1.6ghz atom
for example) combined with the power square law vs clock rate means
that  staying at the absolute top-end of performance (i.e. *ignoring*
entirely the price-performance-watt metric) is about the only option
available.

 they *can't* make profit.  $25 for one of the recent intel "tablet"
style processors - and that's the budget cut-down version that has a
64-bit DDR3 interface and a whopping 650 pins as opposed to a 128-bit
interface with a THOUSAND - where everyone else is aiming for FOUR i
mean they're pissing in the wind basically.
