First, I preface this by saying, I was a Unix Admin in a previous life and have only been working with Windows servers since about 2005.
I took a look at the Windows Server 8 (and Windows 8) betas today and all I can say is this:
Thank you thank you thank you Microsoft. I've been hoping for this moment for ten years and it has finally come. Not only has Microsoft handed more server marketshare to Linux on a silver platter, but they have gone that extra mile and ensured a larger marketshare for Linux on the desktop as well (Windows 8 desktop is even more horrid).
If Microsoft does not significantly change the desktop on the Server 8 beta before release, I see them losing many admins who do not have My 'Lil Ponies wallpaper and Playskool toys piled up in their closet. When I first logged in, I honestly thought my co-worker was having a laugh at my expense and that it was all a joke. But it appears not to be a joke, and even better, it appears that Microsoft thinks server administration is akin to using a smart phone.
The Server Manager dashboard has big bright red and orange blocks and bright circles. At the top left is a location menu, in the top right are menus for "manage", "Tools", "View" and "help" and at the bottom left (or bottom right if the bottom left doesn't work) the start menu. But there are no buttons or any physical indication that there is a start button anywhere. You have to stumble across it while mousing over the bottom corners, then other menus pop up. The reason I say if it doesn't work is because when I mouse down to the bottom left corner some sort of Start button appears, but in my RDP session I can't actually click on it. My co-worker did tell me that I can get to the start menu by going to the bottom right corner, which did work. I do understand that this is a beta. Along the left side of the screen are icons for Dashboard, Local Server, All Servers and File and Storage Services.
One thing I noticed right away is that there is no flow or uniformity in style or ergonomics even on just this one page. I see a drop down menu on the left that makes the left side menu completely redundant, and then a set of drop down menus and a slider menu on the right. So three very different types of interface on one page.
The Start menu, once you find it, is just cute as a button, with the smart phone "tiles" and apparently the only tools a sysadmin will ever need, that being Control Panel, Computer, Task Manager, Windows Powershell, and Server Manager, although I have to guess that there is a way to configure this.
At this point I found out how unintuitive this desktop really was as I tried to log out and run away. My co-worker finally took pity on me and let me know that I had to go to the bottom right corner, then to start, then to my logo at the top right and select sign out.
Most of the server menu items take you to the familiar w2k8 windows and menus, so there is also that disjointed feel to it as well, with the tiles and blocks on one side and the windows and icons on the other (all just several clicks from each other). So as you navigate through to your destination, you will inevitably ping back and forth between tiles and windows enough that neither ever become comfortable.
At one point, I found where the "all programs" was, but for the life of me I can't find it again.
Realistically, when you get rid of the tiles and the Playskool stuff, it's pretty much the same OS that we have worked with in w2k8.
Just a lot less intuitive and a lot more klunky.
