Has someone tried Snow Leopard on the Air ?

[rdubya5]

I don't get it? The original sentence sounds just fine to me... in fact 'Did someone...' sounds wrong as it would imply I am thinking someone has indeed tried Snow Leopard on the Air and I want to know who it was?

The title was fixed, the original was a little off.

You got it backwards. Leopard is 64 bit and compatible with 32 bit.

It's more complex than that, actually. Unfortunately I don't fully understand the details, but the kernel is definitely still 32 bit or mostly 32 bit in Leopard.

The implications of this are not particularly interesting though; it mostly means that *the kernel itself* can't use lots of address space. Applications definitely can, and that's the biggest appeal of 64 bit.

This will start to be a bigger deal as graphics cards ship with more and more vram, since that needs to be mapped into the kernel's address space (so if you have a 1GB graphics card, the kernel effectively has 3GB to use).
