http://www.apple.com/pro/science/gosling/ Count Java creator James Gosling among the converted: I do most of my engineering on my PowerBook, James Gosling states flatly. I find it dramatically more efficient than a desktop system because, on one hand, it has all the power of a full-blown UNIX desktop. On the other hand, I can take it with me because it has all of the laptop stuff. I can work on a airplane, at home, in a corner when Im sitting in a boring meeting. And its able to do not just email and browsing, its got fully-functional, high-end software development tools. Gosling and his development team, he says, almost all have PowerBooks. Its amazing how many of them are showing up these days. Theyve been really popular at work. A certain amount of their appeal is little things. I do a lot of public speaking and the PowerBook automatically does the right stuff when I plug it into a projector. Also the PowerBook is the first machine that Ive seen where the lid mechanism on the laptop actually works. You can close the lid and open it again and its still running. Seems like a small thing, but it truly works.
