The new Air is faster than last year's, with an upgrade to the "Ivy Bridge" line of Intel CPUs, which we wrote about at length here. They'll also start with more memory, at 4GB of RAM (which is not actually that much, really), and gives the option of a 512GB, extremely fast solid-state drive for storage. And it'll get a USB 3.0/2.0 port, a better front-facing camera, and will cost $100 less than before. None of this is super exciting - the Air is an amazing laptop, and this one is, you know, better. Nothing surprising, though. It's available today.

The new MacBook Pro is actually a bit of a departure. At the moment there's not much separation between the Pro and Air lines in terms of price or capabilities - the Pro has bigger screen sizes and some beefier internal options, but not a huge difference. The new Pro line, on the other hand, is kind of bonkers. Its 15.4-inch screen has a a 2800 x 2020 resolution, which Apple's calling a Retina Display. 

It'll be crammed full of the fastest mobile guts on the market - quad-core Ivy Bridge processors, Nvidia Kepler graphics chips, a 768GB solid-state drive, HDMI-out, USB 3.0. It is pretty much the most powerful laptop we've ever seen. It'll also cost US$2,200. To start. To compare: I once purchased a used car for the same price.

We'll update with more info as we get it - Apple's talking about OS X and iOS today as well. Oh, and thanks to the GDGT liveblog for being the best liveblog.
