MacBook Pro with Snow Leopard.

I am a software engineer and use a PC at work daily to develop enterprise level N-Tier applications for use by the Air Force. I develop applications utilizing C# and the .Net Framework. I do backend development with SQL 2005. I say all of this just to emphasize the point that when I get home, the last thing I want to see in my house is a PC with a Windows operating system on it. Windows sucks.... It always has, and it always will. I got rid of my last home PC over a year ago, and hope to never see one in my home again. If you have never used a Mac, then it is hard to understand just how bad windows is. If you have used a Mac to the level that you understand the underlying architecture of the OS, then you get it.
