Another possible split besides High End Users verses Affordable Users, is that Poser 5 takes a giant step backwards in making a program that both Windows Users and Mac Users can both use and swap files. Poser 5's first release is Windows only. This Mac Girl is not happy. Poser 4 was the program of it's kind that I've used which works on both Mac and Windows platforms. Sucks that's changed. How long will Mac users have to wait? And do you have to have a Mac OsX system to run it too? Will I have to buy a new computer just to run Poser 5, or what??? :(
