OS X (Apple)

Panther was awesome, don't get me wrong, Expose is a revolutionary tool, and that alone would have almost made Panther worth the $129. However, Jaguar to Panther was no where near the same magnitude as 9 to 10. When 10 becomes 11 there will be a fundamental change in the way we do things. It will be big, a whole lot bigger than a few extra features (as awesome as those extra features may be).

What about 8-9, though? About the only improvements I saw there was slightly improved USB support and an added Window menu. (I think that Sherlock 2 was a step back, because it launched more slowly.)

Since 10.4 is tiger, 10.5 should be lion, then they could make 10.6 Liger!! That would be funny, at least to me. If you're wondering, Ligers are actually real animals...a mix between a lion and tiger, they are huuuuge...much bigger than either of their lion/tiger parents.

I saw a photoshopped pic on the web of Steve Jobs holding an OS X 10.8 Liger box with the caption "It's pretty much my favorite Operating System."

its my thought that os 11 will be the next big leap in all os platforms. with all the current buzz of physical user interaction, the next major os release will utilize multitouch technology, and a radical graphic redesign best suited for our physical interaction with the computer...

OS X is the system software name. 10.x is the version (you can start version numbers at any point you wish, kinda like check numbers).
Theoretically, the name OS X could never change.

OS X 100000e80.01.99

sweet!

Try Leopard.

Apple - Mac OS X Leopard

My suggestion is that the jump to 11, XI or whatever, should be when they drop PowerPC support.

Note, my Tiger's uname says 8.10.0.
