Wow, impressive.
But, it is on Windows 7, and looks like the encoding software for vids is their own (nVidia's). So it's a great platform, as long as the OS and programs are optimized for it.
I can see the Mini going this route, if they DO NOT come out with an update in March, as an Atom-based Mini is going to REQUTIRE Snow Leopard to run at a reasonable level, not to mention possibly slightly faster Atoms in the Fall...
I've heard Atoms just aren't in the running for multimedia (sorry I haven't got any references, maybe someone out there can find them). Good for netbooks, but not suitable for MacBook Air or Mini.
Look at it's place in Apple's line up. The Mini is not a 'desirable' machine. It's an 'adequate' machine. And I don't see Atom as being 'adequate' for anything 'bigger' than a netbook.
I'd love a quad core Mini (and frankly, that should be the minimum for 2009 Apple releases), but if it's a choice between an Atom and even a 2 GHz Core 2 Duo with GeForce 9400M, I know which I'd be buying.
This is one case where I'd rather Apple stick with CPUs they're already using than something new. And let's face it, quad cores and i7s couldn't look further away from Apple's mind at the moment.
