Depends what you plan on using your laptop for. Do you use a lot of enterprise programs regarding to connecting for work? If you're using it for the basics and want to try it out then I don't see any issues with running windows 10.
I know I had some issues. My Bluetooth driver wasn't working properly and Skye froze a lot. Back to the Bluetooth, I found a fix online regarding to the driver since there were others who had the same issue.
I wouldn't recommend downloading it yet, wait for the next build or two to make sure it's more stable. Because the Preview is usually for developers to test and to send Microsoft feedback regarding any issues in the OS.
