@OP
I have win7x64 on my desktop Main daw. I have Win 8 Pro x64 on my new laptop (I installed it, it came with 7x64)
Ialso bought a Roland OCtacapture for the Laptop and Win 8.
Now, I am NOT talking about performance at all-Right now I am justy going back and forth to get a feel for 8 and see if it changes how I work or forces different moves on my part.
It has not. At the moment they are exactly the same to me (remember, I am talking my workflow here)
The performance part I will evaluate this weekend, but I believe and trust those I know here who say that it's more stable, quicker etc than 7.
BUT, the big but-I wish I had not rushed into installing the media center-I did like a dope and I regret it for my own reasons-mostly because I didn't need it :-(
I can uninstall it but I would also have to reinstall all my apps, so.................I live with my impatience.
I have a copy already for the desktop Dw and that will most likely happen this weekend also.
BTW-the suggestion of using Classic shell, By John and a few others makes the transition simple-as far as working in 8.
