I think I like OS X and Win8
I know this sounds crazy - but I did replace my 13" retina display MB Pro for a Windows 8 machine. I completely got rid of the new Mac for two reasons - one, I wanted to see if I could live without a Mac and perhaps get used to Windows 8, and two, although the 13" MB retina has made design enhancements, I found it to be to heavy (I've been a MB Air user since the first gen).
I think I was also getting a bit bored of not having a unique laptop (I'm in IT - having a cool laptop is a fashion statement

). I ended up going with the Sony Vaio Duo 11 (sure, maybe it looks a bit weird, but it works, and it's different). The reason why I went with the Duo 11 over others was because I didn't want a laptop with a touch screen, like the Vaio T, and from past experiences I know that pure slates, like the Samsung 7 series, are a hassle to carry around and use if you forget the keyboard at home - not to mention that carrying a tablet with an external keyboard around looks dorky.
From a hardware perspective, I'm happy. The computer has 8GB of RAM, a 256GB SSD, a Core i7, a backlit keyboard, and a pretty cool screen. I don't have a trackpad though, which has been a challenge getting used to not having one, and there is no way the Duo 11 (or any Windows machine) lasts as long as a MacBook on battery life - thankfully Sony offers external battery option on some of their models, resulting in more unwanted weight, but a must for travel.
Have I been able to survive without a Mac? Maybe - but I do use my iPhone and iPad heavily, so that might be helping keep things balanced. Am I happy with Windows 8? Yes. I do think I will end up getting another Mac in the near future. I'm going to wait a bit to see if any rumors of a MB Air retina get serious, otherwise, I might get the new iMac.
My suggestion for anyone buying a computer would be to go with a Mac, unless you plan on getting a touchscreen computer. The touchscreen has added another way I can interact with my system, and I've become accustomed to now use a physical keyboard, an on screen keyboard, a mouse, and the touch screen to be quick and productive. I can't really justify the reason for having Windows 8 on a non-touchscreen system, other than perhaps the live tiles providing real time data and the app store.
I think it might be nice for Apple to consider creating a touchscreen system, the added interaction capability could add to productivity if the right apps are created.
If you got this far - sorry for the long post, but being a long time Mac person, I just wanted to express my opinion on using Windows 8 for the last few weeks
