Because my heart wants me to be an early adopter, I'm always extra careful not to be one (hope this made sense...).
I haven't installed Vista yet, nor Office 2007. Now that Visual Studio 2005 SP1 is out, I almost installed it immediately, but I managed to restrain myself and force myself to wait for a few days.
Well, patience pays well, they say. Apparently there are serious problems with the running time, disk space used and disk I/O in general during the SP1 installation. Thankfully, Jon Galloway posted a way to overcome it.
I think I'll wait a few more days to see if anything else shows up and then I'll take my chances :-)
