I'm working on a new MacBook Pro now. it's a great machine and I'm very happy with it. I'm a long time Mac user and OS X came out about the same time I was moving into doing more and more server side code. So having access to unix right along side Mac apps like Photoshop and Flash has been great.

Of course, unix and OS X aren't much help working on .NET applications so for the last few years I've always had a PC laptop for doing Visual Studio work. Even if Mono were perfect, I'd need a PC around to see what Internet Explorer was doing to my CSS work.

Enter Parallels! This application allows you to run other operating systems at the same time as OS X. Having XP right there in another window has been great and made testing a lot faster. There are many other apps out there like GoToMeeting that will be nice to have without having to get out another machine. There is a slight slowness to the video that I imagine would interfere with games but the general speed is great.
