Its cool. A vast majority of Windows users havent used OS X because of various reasons, so i am not too surprised. I've used almost all of Apple's line-up except the Mac Pro's, iMac's, and MacBook Pro mainly because when i got them they were the best. Although i personally don't recommend their laptop lineup, except for the MacBook Air because it is reasonably priced although its competition does have 1080p nowadays, pairing their phone/tablet with they computers/laptops actually work pretty well. I haven't used it personally, but my dad used it so it did look good. I'm not a huge fan of Apple as I've always used Windows and i almost always will use it exclusively unless i have no real option or just experimenting, but I will give Apple respect and credit because they actually make pretty good software to pair with their pretty damn sturdiness of their electronics. But the sturdiness is just an offset from using a ton of Aluminum in the first place.
To get to my point, there are 2 main features in OS X and to some extent iOS X that i really like that would be pretty nice to have on Windows and Windows Phone 8.
1. Text messagin sync. I think it would be great if i can answer my cell phone texts from my desktop, laptop, and/or soon to be tablet.
2. Work spaces. This is a bit nitpicky, but workspaces would be cool so i don't have to switch between writing something in docs and looking at the internet by hitting icons on the super bar and using a trackpad gesture instead. I know metro apps supposed to overcome this but there are really only a very few metro apps that are worth using day to day.
I wish Windows 8 and WP8 had more integration other than skydrive and outlook because that was the really good selling point for getting a WP8 phone. Really, cloud storage synchronization is pretty much there for Windows, OS X, and even Chrome OS so that aspect is pretty much gone to me. A unified market place would be pretty damn dope too. Buy an app once and you could use it on your dektop, laptop, phone, and/or tablet. That would be so dope.
