It's quite awesome anyways. Funnily if you change direction, that alone triggers no relativistic effects.
I think the limitation would be on the GPU side, or at least it was on the system I was testing on.
e: Ah, but it actually runs fine on my 2010 unupgraded 11" Air. I'd guess a higher resolution screen would hurt performance, though.
The person mentioned they would be doing some gaming on it, so I pointed out that the new Air would almost certainly have Intel HD 3000 graphics and that the Nvidia chipset in the older MacBook Air was better overall for that sort of thing.
Someone proceeded to try and rip me a new one, chastising me for having the gall to recommend purchasing a previous generation laptop. I said I owned an Intel HD 3000 MacBook Pro and even on that vs the Nvidia 320M MacBook Air, the Air performed better when it came to gaming.
He called me a liar, said it wasn't possible and that the HD 3000 chipset couldn't be the culprit. Here we are a year later, and I've been proven right countless times. I'm sure this is interesting to nobody, but it's nice to get a little vindication when someone was laying into you that hard.
