if you want a more technical review of the Windows beta, read this: http://docker-saigon.github.io/post/Docker-Beta/
But note that beta 8 was released a few days after that review and already introduced some changes.
Also, for the Windows beta, it very much is still a beta.
I'm sorry for your laptop experience and glad you got it working on your desktop. There are good chances it is related to Hyper-V but would need more info to debug. Could you send us your logs to [email protected]?
Docker for Windows still requires elevated privileges to start. This will be addressed in a couple of releases
Anyhow, I really hope someone does a good overview of Docker for Windows beta, as well as the Ubuntu environment within Windows 10 now...Seems like OSX gets all of the dev love, so I'm wish and hoping for a really nice Windows overview. As I am currently having a hard time with both. Neither, as of right now, work well.
