The good:
New aluminum construction looks good, feels solid; giant touch pad; attractive edge-to-edge glass on display; improved integrated graphics; backlit keyboard on some models; thinner than previous version.

The badThe bad:
Still no ExpressCard or SD-card slot; loses FireWire port; all-clicking touch pad is a bit awkward, at least initially; $1,299 now gets you a slower CPU than it did before; no matte-screen option.

The bottom lineThe bottom line:
Apple's redesigned 13-inch MacBook is essentially a shrunken version of the more expensive 15-inch Pro line. With its new aluminum body, new trackpad, and Nvidia graphics, it's an even more attractive choice for mainstream laptop buyers than was the plastic model it replaces.
