Some issues I'm noticing with 7048 x64 - The network just drops out occasionally necessitating a reboot. - Access to shares on certain servers would be gone, while I could access others just fine. Restarting the workstation service got it back to normal. - I've got one machine that will completely lock the UI if I attempt to play any youtube videos. I have to tell it to shutdown. This allows the process to be killed then I can cancel the shutdown.
Am using it (testing it) in a production environment - works fine so far, except for a minor irritants - none of the probs mentioned above..!
