Yeh I wunna strike upon the head the person that said "hey, now that every mac in our lineup is going to be metal, wouldn't it make sense to drop the metal theme?"
I'd like just one thing, optional themes supported by Apple!
As for the argument MacOS requires more resources to have pretty effects, ONE, if you pay attention you realize it ISN'T all gussied. The only difference is the color scheme, nothing advanced. With effects like stacks and expose, with OpenGL this stuff is SUPER light on any system.
Sys Reqs.
-Vista (Considered "capable" of running Vista)
CPU: 800mhz
Memory: 512mb
Disk Space: 15gb
-Leopard
CPU: Not actually known as it only says it supports ANY intel Mac, the lowest being 1.5ghz, or a PowerPC 867mhz or higher.
Memory: 512mb
Disk Space: 9gb
-7
CPU: 1ghz
Memory: 1gb or 2gb for 64-bit
Disk Space: 16gb or 20gb for 64-bit
-Snow Leopard
CPU: Not actually known as it only says it supports ANY intel Mac, the lowest being 1.5ghz.
Memory: 1gb
Disk Space: 5gb
Let's not forget, if you're running Windows Vista or 7 on a low-end machine it has to cripple the OS, I guess to make it look good on paper. Scheming @#$%&
Also, if you are a Mac user, when time comes to upgrade to Snow Leopard the ONLY questions you have to ask is "Is it intel? Do we haz 1gb of ram?" So simple.
