MacBook Air is ultrathin & ultra streamline.  It's the result of rethinking conventions breakthrough design. With MacBook Air, mobile computing has a new standard.
MacBook Air is nearly as thin as your finger. But still has a 13.3-inch widescreen LED display, full-size keyboard, and large multi-touch trackpad. It's portable without the usual ultraportable screen and keyboard compromises.
The incredible thinness of MacBook Air is very surprising. From a slimmer hard drive to strategically hidden I/O ports to a lower-profile battery, everything has been considered with mobility in mind

Introducing the new Mac mini. Just connect this tiny 16.51-cm-square Mac to your own display,
keyboard and mouse, and youʼve got an instant desktop computer loaded with Mac OS X Snow
Leopard and iPhoto, iMovie and GarageBand. The new Mac mini features a faster processor – up
to 2.53GHz – and twice as much memory as before. It also comes with up to 320GB of storage

when idle.
