Seems to me these improvements are TBA and TBC. Just like Sonar some feature, improvement or major performance benefit will come around one month which I might like, which could make me want the product.
The only thing that makes me want Windows 10 right now is a) My aging Win7 office laptop needs rebuilding b) It's the latest OS.
For a DAW environment I guess if I was running Windows 7 I might see a significant performance increase, but I'm yet to be convinced from 8.1
Later on I will need it because I want to run a supported OS as long as possible, and I'd prefer not to pay for it.
