4.0GB partitition too small for Longhorn & VS.NET Whidbey.

I installed my Longhorn on VMWare with a 4GB partition (thinking in terms of "Hey, it's one DVD for backup"). That's too small for Longhorn and a reasonable install of VS.NET Whidbey (If you install nothing but the minimal C# support, you end up with 3.93GB consumed!).
