If you are playing with Windows 8 make sure you check out:
In addition to that Metro apps shipped on the consumer preview kinda go wonky after joining the domain.

Bottom line when you join a Windows 8 consumer preview to a domain Metro kinda loses it's mind a bit.
I like Windows 8. I think it's a good operating system, and I'd like to see more put towards business support of Metro. Once the majority of LOB apps are written for WinRT, I think it'll be a very solid OS. That said, I think there isn't enough emphasis on supporting business usage scenarios for things like authentication and cloud service support. I can use a Microsoft Account ID and have this auto-magical roaming profile that moves with me from machine to machine and it'll pull all my Metro apps, but how easy is it to set that up in Windows Server 8 for managed computers and domain logon? When are Office 365 logins going to be switched over to Microsoft Account ID's so that we can use them to log into the computer too? How about tying those to the local domain accounts so that we have one login? Where is the SharePoint/SP Online integration to replace the consumer SkyDrive app? Why don't we have a business-centric App Shop feature where IT managers can give users access to the shop but manage exclusion lists by categories or by white-list or black-list?
Are BYOD setups supposed to rely on the Metro Mail app for Exchange in place of Outlook? What about licensing for the ARM version of Office that's going to be included on WOA devices? Will it be legal to use within a business setting (it looks like a Home & Student copy, which isn't)? That's going to be a big "gotcha!" if true.
Also, one thing that people probably don't remember: Microsoft instituted a 5-device license for Metro apps. One of the reasons they are keeping the desktop is so that software vendors, including themself, can still sell desktop software that doesn't abide by that multi-device license scheme. Imagine if AutoDesk or Adobe had to include 5 licenses for every purchased copy of their pro software? There would be a major developer revolt then - or prices would skyrocket. Even Microsoft knows that they would lose money on Office licensing by making it a Metro app. Office, not Windows, is their biggest cash cow after all.
