I have a terrible secret. For the last few months, I've been using a... Mac (gasp).
Now I may be the only mac-user on this blue ball that isn't some sort of die-hard apple cultist. I think they're great (if over-priced) hardware, and I dig OSX. I don't think Steve Jobs is the second coming. I hate iTunes and iPods. I don't have an iPhone. I don't like black turtlenecks.
But this does make a nice little web development machine. I have a command line (that's not DOS...) and a unixish OS. It has apache set up right away. It has a very nice UI, and there is some amount of "it just works" - although I'm not sure that's more true with WIndows. But it is more true than of even the best linux distros, at least in my experience.
So, stay tuned and I'll point out some handy apps for any other web devs who've made the switch.
