I use Windows 8 on a Lenovo touchscreen laptop and have Mac OSX Yosimite on my iMac. Honestly I use the Windows 8 more, love it on a touchscreen and it utulizes hardware really good actually. Took getting used to but after using it for a week or so I really liked it a lot. Mac OS isn't too bad but don't think it's all that and I prefer the Android and Windows store over the App Store. Think the App store isn't as easy to navigate and I see things on there that you have to buy but is free on the other two. Also some of the prices (I don't mind paying and supporting the developers) are ridiculously expensive. Don't get me wrong I do like some of the stuff but am truly grateful to have all three (plus my beautiful Amigas of course that are my ultimate love

and be able to have access to everything out there (some stuff in App store not available in the others, but not that many anymore honestly). Cheers
