Oh, plastic MacBook, how we've missed you...

Apple has made a bunch of changes to their base workhorse, including:

A polycarbonate unibody upper case

An LED backlit display with the same 1280x800 resolution as previous models

A glass multi-touch trackpad

An integrated lithium-polymer battery

Non-slip coating covering the bottom panel.

The case revision also allowed Apple to update the aesthetics on the new Macbook. Its contoured edges fit right in with the rest of the unibody lineup.
