Downloaded and Installed the DSM 3.0 beta from synology beta site.
I performed the upgrade remotely as I am away from home at the moment. Have to say was seemless as I expected.
The new interface is as slick as I thought it would be as I has a sneak peak before the launch.

I will be testing it out over the next few weeks and be a good beta tester and report back to synology.

2 minor issue found already but nothing to be concerned about.

All in all this is a major leap forward for Synology and the diskstation user experience.
