Anyone ordered it yet? I've ordered my copy

See it here: http://www.apple.com/au/macosx/

Discuss! Do you think it will be a good upgrade? Anything you know about it and what not

"The worlds most advanced Operating System"

Lolnope.

I'll definitely be upgrading to it when released
Looks to be good. Yaaaay.

does mac OS support dx10 for games? does a mac even have a pci-e port?

there is a shitload of games and programes out there that REFUSE to support mac.
mac fails.

GT120, GT130's and HD4850's come as an option in iMacs.

Too bad there is no games.

Macs certainly do have PCIe. Most game shops out there don't support Macs because there simply isn't enough Mac users out there to make it worthwhile. It is a simple case of Economics and nothing to do with OS X.

Any game developer worth their salt should have no trouble developing cross platform support these days.

Hell, Diablo 2 runs on PPC ffs.

Blizzard have been making games for the Mac for years. Big kudos to them! I agree, there isn't much excuse to not being able to develop cross-platform. Game developers have been doing it for YEARS between the PS2 and Xbox! However, I think there are still more PS2s and Xboxs floating around than macs.

Even though windows has failed hardcore with Vista... Windows7 seems to be ok.. for now.. and i'd still prefer it over a Mac OS anyday without question. shit id prefer ubuntu over mac os.

Upgraded my Hack Pro to SL yesterday, runs really well in 64 bit. Just need to get some drivers for my 3rd party stuff.
