Just before JavaOne, I replaced my venerable G4 PowerBook with a black MacBook, and I've been pleased with the transition. (At over three and a half years, the PowerBook had an exceptionally long useful life for a laptop.) A few observations:
- A 2.0GHz Core Duo is more than fast enough. In fact, while I wouldn't have expected it, the MacBook handily beats my 4-way G5 for many development-oriented tasks like builds and starting up IDEA.
- Battery life is essentially the same as with the PowerBook, a little over four hours at minimum screen brightness.
- MacPorts, rsync, and the usual downloads (Aquamacs, Quicksilver, Adium) made it quick to get a usable configuration up and running.
- Just like the PowerBook, it's too damn hot to be truly used as a laptop without some additional insulation.
- The keyboard is odd, doesn't light up, but is otherwise tolerable.
So far, so good.
