Holy crap! Microsoft has put out public beta's of the Whidbey IDE in the form of several smaller packages called Express Editions. This could be great for those of us who don't have MSDN accounts (yet) and haven't been exposed to Whidbey directly.
You have to jump through a few hoops to get them (Passport account and a survey), but they are otherwise free for now.
I'm downloading them now, I'll post my impressions later.
