Uhm, no it's really not.
The Apple iOS is built off of a unix daemon more of a BSD style. The hardware is nothing related at all to microsoft. Microsoft doesn't even make hardware.
The hardware is custom made in how it's API ties into the software using Open CL which is a newer version of C and C++, which isn't proprietary to anyone or anything, hence the Open, which is why it works correctly all of the time, which is why there are far less software updates for the Apple. Apple was 64bit processing before Windows could even think of doing it in a non-server platform (Windows 2000 and Windows 2003) thus making use of the dual-core processing before Microsoft was adding it to smaller end machines, again, non-server platforms of the OS.
What makes you say this, your comment couldn't be further from the truth in all honesty.
