I would recommend holding fire for a few more weeks and waiting for the release of Adobe CS4, as this will be the second iteration of the current Mac compatible Premier Pro and is reported to be a much more integrated solution. However, CS3 is no slouch and made a welcome return for Premier on the Mac.
Whatever route you choose I would advise running the native Mac version – even Adobe commented on how well Premier runs on a Mac in comparison to the PC. Although I myself am a PC user, I would refit our PC gear with Mac hardware like a shot if I could warrant the outlay – far fewer “unknowns” in hardware conflicts and a much more efficient OS, in my opinion.
Hope you have a pleasant return to Premier.
