If I drank coffee I would be cleaning it off my keyboard now. Snow Leopard is "pure?" Funny. Only a few years ago Mac-oriented forums were full of people complaining about how superfluous, disappointing and misguided Snow Leopard was. Leopard was the end of the line for the "real" Mac OS and the "real" Mac users that Apple was abandoning. Of course, two years before that Leopard was the pretender king to Tiger's pure goodness. Oh, wait: Tiger had its detractors, too. So did Panther. Few people complained about Jaguar or Puma, but Mac OS X itself spelled the end of the line for the "pure" Mac experience once. But that's okay, because so had Mac OS 9. And 8 and 7. 4-6 were relatively low-key releases, but 3...that annoyed a lot of people. (Folders and 31-character filenames screwed up peoples' workflows something fierce. No, I'm not kidding.) The Mac itself? Oh, that was an awful machine that wasn't compatible with anything else, didn't look or work like any prior machine that a typical user of the day understood and insulated you too much from the reality of the computer - preventing you from getting real work done. Clearly Apple was dumbing down computers for the ignorant, lazy masses and thumbing their corporate nose at their loyal users in the deal.
You're going to have to help me understand what qualifies one OS version as more pure than another. The Apple *I've* known and dealt with for 30+ years was quite literally founded on the principle of disruptive change.
