Everyone knows the Mac was reverse-engineered from captured alien technology in Area 51.......no, seriously: the mac was developed by and for visual designers doing creative tasks with photos, art, video and audio. The pc developed as a system for creating, sharing and storing informational files, and until relatively recently was rather slower and poorer at the purely creative stuff. New pc's and programs for pc's are more like macs nowadyas, and they have become much better at the creative stuff than before. Macs have always included all the extras which were traditionally add-ons for pc's, like cd reader / writers and video editing programs, and macs recognised any usb device automatically. Many of these features now exist on windows XP pc's so the differences are narrowing. Lastly, it is relatively easy to find out how to build your own pc, but mac technology is not widely shared, probably 'cos the aliens copyrighted it.......
