Comparing XBox with XBOne, it looks like after all making a PC-like console can actually be a good and profitable idea, as long as you don't buy the CPUs from Intel and you don't sign horribly one-sided deals with NVidia for the GPUs. Otherwise, better sticking to PowerPC, without adding too many funny things to IBM's fine design (and Motorola's too, credit due for the original PPC project).
