I'm waiting for the Linux crowd to weigh in and say that the Penguin will devour both the Mac and Windows. I haven't used a Mac since the 680XX System 7 or so days. I wasn't impressed then but I'm sure OS X is a fine system. Unfortunately, as Ratteler alludes to, Apple's marketing strategy killed any chance of the Mac being a dominant platform. They've made a magnificent comeback, starting with the iMac. But, for those concerned with (as my old beloved Atari used to say), "Power Without the Price," aren't going to pay the 2-3X premium for a Macintosh. I run Windows 2000 and VMWare which allows you to run Linux and any Microdoft OS (from DOS to XP) in a virtual machine environment. Works quite well. If they could add Mac compatibility, I certainly like to try OS X. One of my main hopes for Poser 5 is that they drop the tidiculous cross-platform compromises and have true Windows dialogs for the library, etc. Each version needs to work the way native applications on the respective OS do.
