Well, I jumped on Win8 very soon after its release and I have been using it for almost every day since. But to tell you the truth, getting Windows 8 made me buy a Mac.
Not because there's anything wrong with Windows 8, it's very stable, all my hardware works without a hitch, I haven't run into any incompatible software, it's the perfect system - performance wise.
But to me, it just interacting with it, I seriously can't stand it! It has some ways that to me seems not only illogical, but quite ridiculous as well. And the added features like integrated cloud service etc, doesn't work as well as I want it to. I get loads of errors when saving files to sync with OneDrive. The OS over all just feels like a stupid and fat donkey that I have to drag around. But then again, no OS is for everyone.
The 8.1 update made Windows 8 a whole lot easier to live with which is why I haven't gotten rid of it already but during my next system clean up, there's a HUGE chance that Windows 7 will find its way back. Unless I sell everything and try living with OSX for a while.
Having said that, I have Windows 7 on my Macbook running Sonar, and I am very happy with that. But Windows 8 - I just don't like it. But if you can get Windows 8 for a good price, it is well worth checking it out. Just keep a system image of your current install at hand
Good luck!
