in case you're wondering if I bought a Mac yet

The Air is pretty, but it's got a smaller HD and a slower CPU than the entire MacBook range. I priced Mac + AppleCare + (in the case of the Air) enough hardware (ethernet, Superdrive) + whatever that music software is they're bundling for a coupla hundred, and by the time you've kitted out the Air you may as well be buying a Pro and you've still only got a 13" screen and a 1.8GHz CPU. So, I will not be buying an Air. Repeating what I said on my geek diary for today (or will have said once I run the uploader), at this point I'm leaning towards a regular MacBook because I don't actually need the extra GHz of the Pro, and the difference in screen size is the only thing it comes down to. And my back-of-the-envelope calculation says that the Mac's 13" Widescreen display isn't massively smaller than my current laptop's 14.1" 4:3 display. So now I am in the "thinking about it" phase.
