"Windows 8.1 is the best OS Microsoft have ever made despite what the troglodytes say."
In terms of what's under the hood I can agree with that, it is much quicker and more efficient, night and day compared to 7. Sadly the schizo UI where both flavors are partially complete is a clusterfunt, it reminded me of the worst Linux desktops from over 15 years ago for all the wrong reasons. :(
It's not just me either, our kids (all <7) find Win 8.1 tricky, but they're fine with Linux Mint & Mate when they borrow my lappy - despite spending 10x more time using 8.1.
