Hi. I'm running Leopard on a MacBook and am going to get XP and parallels. My question is if I should invest any time/effort/disk space on another one of the supported guest OS's as well. Since this would be easier to answer if you knew more about me... I am, naturally, getting XP because I want compatibility with various Windows Programs and Games. I plan to use XP with Coherence most of the time, since I'm a big time Mac user. I understand this is currently unavailable with other guest OS's. I'm pretty much a jack-of-all-trades computer user, although I have very little experience with actual programming and non-mainstream OSs. I also doubt I'll do much compiling with source code since I'll have both Leopard and XP working for me. I guess what I would mainly go for is a OS with advantages/differences from Leopard and XP. I was considering freebsd because it sounded neat, but I noticed that the compatible versions are a bit out-of-date. So, that's where I am. Let me know if I need to clarify anything. I'm new to the whole Parallels scene. Thanks!
