"How friendly? I've already been using SLED 11 for a
few days and I can now say that you can manage SLED workstations
with AD (Active Directory); read and write Office 2007 file
formats; watch and listen to Microsoft Silverlight and Windows
Media videos and audio; and work smoothly and fully with Exchange
server. SLED's the closest thing you've ever seen to a Windows
desktop that's actually Linux. For more on that, look for my SLED
review in ComputerWorld later this week.
"Novell and Microsoft's partnership doesn't stop at the desktop.
Novell states that SLE will run at near-native performance on
Microsoft Hyper-V virtualization. While I haven't done any
extensive testing of this, I have used a SLES 11 beta on Hyper-V
running on Windows Server 2008, and it was darn fast."
