The PowerMacs used to be high end computers and Pros used to use them. But there are things nowadays which Intel Macs take a few mins or an hour or less to complete compared to HOURS from the G4s (for example). Those tasks which used to take ages to complete are considered low end tasks today and are completed in very little time. My question here is that what are the tasks that we carry out today, which Intel Macs still take say hours to complete? If we fast forward into the future, the latest Macs of those times would be able to finish todays tasks in very little time.
