you get all the upgrades for free through the update-thingie, but with leopard it's a new os, not just an update....!
I'm most likely to buy leopard when it comes out, though I'm going to wait just a sec to see what it's like!
I don't look down on softeware pirates, but I would never pirate something which I think is great and use all the time! After switching to mac I even found soo much great shareware - I never used that on PC, and I still find a lot of good freeware as well...
So I have no worries having to pay for my OS, especially when it is as good as OSX!! I dread the day Apple sees OSX as bad bussiness, starts to neglect it, and it turns into a easy breach just like winblows!
Also I have this weird fetish - I just have to have the original "cover", just like music I just gotta have the cover - that's why I never really liked buying mp3s but love CDs...
