My friend is considering buying a 2000 G3 Powerbook from a friend. It is a 333 mhz, 64 MB RAM. His friend is offering to sell it for $500. Is this a good buy? I can't remember the other specs off hand. Also, should I even waste my time buying anti virus software for my iBook? I get an ed discount and get two software titles per year discounted. So far, I am getting OS X.2. That means I get another one. Should I get antivirus software or just get something cool like Flash?
