Of all the things they are/could be doing wrong this is your dealbreaker? As long as performance and power management are comparable who cares if the architecture is ARM or x86 (or MIPS, PPC, SPARC, whatever)? Sure, current x86 chips don't have the power management features of current ARM chips, but there's nothing in the instruction set that dictates that, it's simply that they have been targetting the PC market so far.

Oh, and for all their faults Intel is much more open than ARM/TI.
