For those of you too cheap (or too far away) to buy a copy of this month’s Macworld on the newsstand, here’s my latest back-page column:
This history is analogous to that of the automobile industry. In its early years, the state of the art advanced at a remarkable clip. Today, new cars come out each year, but with small refinements. Those changes add up: a 1997 car (even in mint condition) is clearly distinguishable from a 2007 model. But a 2005 and a 2008? Not so much. That’s pretty much where we are with OS X. Tiger is the 2005 model; Leopard is the 2008.
