Ok, if you're hiding from kids suffering from sugar candy hangovers I have a challenge for you - and, especially for those who like and use Microsoft Windows on a regular basis.
The challenge is this: offer a list of anything new in the Microsoft Windows 7 M3 pre-beta release for desktop use sometime in 2010 that doesn't work on a Mac laptop now.
From personal libraries and gadgets to gesture support, it looks stunningly familiar - and if, like me, you don't have personal access and have to go by third party reports, here's a whole bunch of google hits on stuff by my fellow zdnet bloggers - everything from leg tingles to comments from Microsoft technologists and all with lots of helpful screenshots.
Good Luck - oh, and if you can't find anything that's exactly compelling? well, then there's probably something you should be asking yourself, isn't there?
