Windows Vista

I have now been looking at EVERY release of a new Vista beta or Release Candidate, including installing the first version that we got at the PDC 2005 in my hotel room just after receiving the long-awaited DVD set. Latest installation experience is RC1 of Windows Vista. Expectations were mixed,as the previous versions all had some oddities. But this version is fast and responsive, although i am not sure about the broad acceptance of the new UI. Also, increased security features are great, but it should be kept in mind that the huge installation base of Windows probably exists due to the ease-of-use (no root accounts, no "switch user" like with unix, no file permission settings etc.). After experiencing frequent DNS timeouts today, Windows couldn't repair the network, but Windows Help then told me to open the network properties window, open TCP/IP settings and enter "root" credentials if requested. THEN close the window again without modifying anything.... That means to me that regardless of all the security popups (which are a bit annoying at times, but a good thing security-wise), the Network connection apparently couldn't acquire administration rights and needs the user to just open properties. Apart from the fact that it was real luck that i've for once looked at the help text, this action makes neither sense nor can it in ANY way explained to an average user. Why doesn't a network connection ask for Administrator details when set up by Vista automatically ?
But apart from that, using Windows Vista is much more fun, especially for the eyes. i'll keep evaluating ;-)
