Well, hard choice, but probaly yes, unless you had some compelling reason for staying with a Mac, like also doing DTP stuff (where a Mac is far superior). While I've never had any problems using PC Poser stuff on my Mac there is a lot of stuff I do that is a major problem, just hand editing a CR2 in simpletext means you have to run it through Mac Converter twice (or once if you use Word), PCs can just edit on the fly while in Poser. Also, my Mac was supplied by where I work, but bottom line is a 500 Mhz Pentium III is about twice as fast in Poser as a 400 Mhz G3 or G4, and cost roughly half as much. Hard to argue with that, and I really don't think System 10 will improve on the situation at all, other than less crashing. I'm the main support guy for Macs where I work, and while I love 'em, anybody buying a new high-end Mac for anything else than DTP or teaching DTP is a fool. The low-end Macs are fine, as long as you just want to do low-end stuff (like web surfing or word processing) with the Mac's superior interface, but for Poser (which is a high-end application, even if it doesn't cost $3000) they don't fly.
