Today Visual Studio 2008 went RTM and made available on MSDN Subscriber Downloads. Most of the morning, MSDN had problems keeping up with demand and was down until around 10AM EST. I finally got mine installed around 10:30 or so this morning and so far so good. It was just frustrating while I was getting ASP.NET server errors exposed to me while I am trying.
has a pretty good post on the release.
