Silly comment; but to respond - Cost, size and power requirements ?
The closet Intel CPU for Pi 2's is N270 my guess, N270 runs Linux and Hackintosh(yup) quiet well, but I have to wait for 30 seconds to boot up the Windows, even if I'm using XP.
N270 is a single-core 1.6GHz Intel Atom CPU used in old netbooks (I used to have 2 which have since died), Pi 2's CPU is a quad-core 900MHz (1GHz overclocked) ARM Cortex-A7. I'm quite sure the clock speeds do not directly compare but the ARM Cortex-A7 is slower per MHz than the N270.
Performance-wise they are quite close for general purpose use, thanks to the quad core ARM, but when it comes to emulation, single-core performance is what counts, so the Pi 2 would most likely be considerably slower for that purpose than an old Atom netbook. Emulating x86 too is necessary on the Pi 2's ARM but not on the N270, which is native x86, so while a N270 can run Windows XP well, a Cortex-A7 can NOT.
