My experience and opinion,
is that windows is:
- more difficult
- slower
- less secure

Than apple OS. I also love apple hardware. But too expensive for me.

Android doesnt get enough security updates (my phone will forever be stuck on android 4.2.2 and i don't want to get into running custom roms).
If android would get updated, then I would have definately bought an android transformer,
because android is also more user friendly in my opinion.
Except when you want to download and move lots of files, then windows is better i think
