Okay... I installed Windows XP instead. Vista still has too many quirks on my laptop. Maybe after SP1 reaches final, I'll give it another go. Until then, I'm back on Windows XP after several months of being really happy with Ubuntu Linux (Gutsy Gibbon). The reason I'm back to XP is that I found myself really missing Visual Studio for development. MonoDevelop just isn't "there" yet as far as I see it.
Pretty happy to see that Windows Live Writer also exists for XP ;)
