Ben Gutierrez writes "Paul Graham has posted a new essay on the Return of the Mac which begins with: 'All the best hackers I know are gradually switching to Macs.' Tim O'Reilly said some similar things in Watching Alpha Geeks . From the article: "My friend Robert said his whole research group at MIT recently bought themselves Powerbooks. These guys are not the graphic designers and grandmas who were buying Macs at Apple's low point in the mid 1990s. They're about as hardcore OS hackers as you can get."
