Looks like Longhorn will be the first .Net operating system - no more will we have to dig around and P/Invoke the Win32 API. Those days will be all but gone - managed Longhorn interfaces will finally put that to rest, thank God. Combine that with Aero, Avalon, rights management, a shift toward service-oriented software design, WinFX ("an evolution in the .Net programming model"), WinFS file system based on the brand spanking new SQL server Yukon, XAML Longhorn markup language - damn have I said enough? I think Microsoft finally hit the nail on the head with this one - methinks .Net is finally starting to make some sense business-wise.
