The developers at Redmond must be working around the clock these days. They're releasing software at a pace where it's "hard work" just keeping up - the most interesting (I think) the last couple of weeks are:
I upgraded my computer to Windows Vista Business (32 bit) - And to my big surprise (almost) all my devices are supported, however some of the old utilities needs to be "Vistalized", so I Googled a bit for some Vista utilities and came across WINDOWS VISTA Software Archive.
Especially the (free) screencapture utility WinSnap is highly recommended.
Also .. if you're wondering whether .NET 3.0, WPF, AJAX, Gadgets etc. is worth your while, you should check out the "Dinner Now" sample application Microsoft have put together - Go to www.dinnernow.net and take a look at the video, awesome stuff .. and best of all CodePlex contains full source code for everything!
