I know this must have been discussed somewhere before but I am debating between a PPC unit and an Intel (both Macs). What concerns me is that some of my apps and shareware will eventually go native Intel only and eliminate PPC architecture. I read something the other day that impressed that on me. Is there any need to worry for the next 2-3 years or more? Is there any patterns being set now that point to that possiblity of no more PPC support?
