Really, why should they? If they are doing what they say they are doing, this is far huger than a bunch of new applications and a new theme. This is setting up applications to tap into all those clock cycles on the CPU and GPU that are wasted, this is improving efficiency. What Apple are doing with Snow Leopard is the biggest change to the software side of desktop computing in 10 years. Secondly just because Leopard had a lot of new features over Tiger it doesn't mean that was the same in the past. Lets see, Panther, a new Finder, Expose, new Mail, $129. Tiger, Spotlight, some 64 bit support $129. Thirdly, how can you even begin to say that you wont pay $129 when you haven't even seen it demo'd? Fourthly, like with any other product in the world, if you don't think its worth it, don't buy it, and for god sake, don't bitch about it. No one's forcing you to buy it, Leopard will not cease to function the day SL comes out. A $129 for the best OS in the world is already too cheap, and no that is not arguable.
