I'm wondering whether it's practical to get a Mac Pro at this moment in time. Will EVERY application, including all the less popular applications and shareware, that work on my G5 also work on the Mac Pro? If the answer is yes, then what are the drawbacks of moving to a Mac Pro now? I hear that many of the major applications either will not workon the Mac Pro or are much slower. Does anyone know all the answers? Is there a simple explanation or rule of thumb that can be used to decide these issues?
