When I started to interact with my friends about Visual Studio 2008, there were several questions raised by them, like,
1) Will it work in Vista ?
2) Is it not better to wait for a Vista patch like Visual Studio 2005 Service Pack 1 ?
3) Well, do you really think it will support .NET 2.0 and 3.0 ?
4) Will my Visual Studio 2005 solutions work in Visual Studio 2008 ?
I would also highly recommend to download the Visual Studio 2008 and .NET 3.5 Training Kit by Microsoft
