This is written on a spanking new MacBook Pro, the 2.33 GHz, 2GB version. Company issued, mind you. Now if that is not a good reason to work for Valtech, I do not know what is.
The main reason I upgraded from my trusty 1.67 GHz G4 PowerBook was not speed, it was the possibilities of Parallels. I do quite a bit of evaluating and demoing of server configurations, and having it all available locally is a complete killer.
The first virtual install was Buildix to convince a customer that Subversion and Trac is a viable platform.
But of course it is wroooom-fast. Extremely responsive, and not hot. I currently have it in my lap - no problems what so ever.
