The speed increase is noticeable in a bunch of different applications. Compiling the Lux sources takes under half the time on the new book versus the old one. Since the MacBook has an Intel chip in it, I can also run Windows on it (purely for testing purposes). I bought Parallels Desktop, so I don't even have to reboot; Windows can just be run inside a window of Mac OS X.

I've been lusting after a MacBook Pro since they were first released. I told myself that I would hold out for the first revision, to avoid any early model problems. There turned out to be a variety of issues with the first generation models, so it was a good move. As soon as Apple announced the new models last week I jumped on it like a fat kid on a smarty. So far this one is rock solid (knock wood). I'm even working with it on my lap, and it seems cooler in temperature then my Powerbook was. Time will tell the full story of course. For now: Kick ass!
