Mark Pilgrim is ditching his Mac. Tim Bray sounds like he may not be far behind. I became an iBook user in 2002, but I've mainly used my laptops as though they were Linux systems which just happened to have better hardware-OS integration, dirt simple networking, and a slicker desktop. At the 2003 MapServer Users Meeting I plugged the overhead projector into my iBook and drove the presentation directly instead of converting to PowerPoint to use the conference machine. In many convenient ways, it just works. On the other hand, I've always preferred Mozilla and Firefox to Safari, and other than iTunes and Mail.app don't make much use of the Apple app suite. I don't think I'm quite ready to unswitch to a Linux laptop, but I'm getting close. The Python experience on OS X has always been crappy, and Apple's love of DRM annoys me.
