I miss "whidbey" but I still use that fond old nickname for Visual Studio 2005.

I really like "avalon" [Windows Presentation Foundation]

After those light, airy, winsome names, these new ones are like sitting in a dark cigar smoke filled room with big leather chairs and a lot of fat old men chuckling about the stock market.

Boo hiss.
