There's something that's been bugging me, and it's this:
Look at us all, sitting here, ready to buy the new OS X...
Apple pitted Leopard against Vista with pithy remarks like "Redmond, Start Your Copiers", oh how we smiled...
Then Apple says, "here are 10 new features, also there are some top secret ones". We all go oooooooh!
Then there are delays
Then the top secret new features are nowhere to be seen.
Now unless they've been seeding one version to developers and developing extra features on the side... which is highly doubtful, then Leopard stands to be Apple's Vista...
What I mean to say is, XP/Tiger works fine/great - but Microsoft/Apple thought of a few more things to add. Then they realised it was going to be harder than they thought, delayed the project, and ultimately dropped a bunch of cool stuff. The main difference is Apple were smart enough not to tell anyone what they were developing so they could drop it easier...
No?
