Windows RT vs. Windows 8 boot time...it's loooong
It's takes around 30 seconds to boot into start screen on an x86 chip Atom Clover Trail.
While a full minute on an ARM chip QUALCOMM S4 dual core.
Didn't totally see that coming, but I guess WinRT is still not as optimized on ARM as it is on x86. In comparison, the Galaxy Tab variants boot up in around 30 secs.
