I'm not a huge fan of the AIO form factor since I typically spend a lot on a display and keep it for a long time, but I was actually waiting for an Ivy Bridge iMac. I finally gave up when ML came out.
The Hackintosh is working amazingly well. I had a lot more trouble than I expected setting it up, the community does need to work on the docs a lot better. Once the hardware was ready, it took me about 10 hours to get the OS installed properly. Now that it is, it's perfect, the more difficult stuff like sleep mode and the app store work. It's just like a mac in every way except it's faster than any mac on the market (i7-3770k).
I do a lot of photoshop work on it, but where the mac really shines for me is in what it can do out of the box. I want to load an iso image...mac opens it right up, windows I need to download a utility. Open a zip file, same thing. Over the years I've had the same experience playing DVDs, burning discs, and a thousand other tasks where the mac just does it, windows I need to spend 15 minutes finding a utility for it, usually end up with spyware or a toolbar I don't want and in the best case I just bloat out my windows a bit more.
For that reason alone I'd much rather use macOS than windows, but I'm at the point where mac means I lose USB3, a desktop video card, DIMM memory slots, a decently powerful computer without a monitor that doesn't cost more than a good used car. It's just too many tradeoffs and mac just isn't worth buying anymore. And now this iMac rumour makes it sound so much worse.
