We are going to be switching from PC's to Mac g5's in the coming months here at work. What I was wondering was this: We have full versions of many graphics apps for the PC, like photoshop for example. Is it possible to upgrade photoshop to the mac version, instead of having to buy the application all over again for full price? Has anyone gone through this yet? I plan on calling adobe anyway, but I thought i'd ask here first for some feedback from anyone who has done this.
