Microsoft launches Windows 8

Compatibility issues with what? I've not had any problems passing documents or images back and forth between Apple and PC programs.

That's only because it's a very different look from PC. It doesn't take any more technical skills to pick it up than learning PC and that's why Apple offers in-store and online classes up the wazoo to help (and lay people have created hundreds of YouTube tutorials on their own as well) - they've got the greatest customer support I've ever experienced. I've gone in and gotten classes on how to create movies, photo albums that are then published like a professionals, how to use their document programs, email, internet, they help with transferring files from PCs to Macs, etc. Any software you need exists in the Mac platform, either as an alternate to the name you know (like Adobe Acrobat), or as a similar product. My son recently spilled Sprite all over my laptop on our way to Iowa last month, they told me to bring it in and they'd take it apart and thoroughly clean it for me, for free. It's not so scary once you start playing with them, and that's the best way to learn!
