2.16 GHz Core 2 Duo black MacBook. Upgraded with a 320 MB hard disk and 4GB of RAM (can access 3--see screen shot in photos). Comes with fresh installs of Snow Leopard and Office 2008 with all subsequent updates, plus iWork '08 and iLife '08. Also comes with Higher Ground Shuttle laptop bag.
The machine is very clean--the trackpad has some shininess in the center, but most of the time it was used with an external keyboard so the key caps are unworn (see photos). Its only flaw is that the third-party battery loses its charge after a couple of days when sitting around disconnected and unused--it works fine when connected to power, though, and the fully charged battery gives nearly 2 hours of use, but it.
This was a regular work machine until recently, and could handle a dozen tabs open in Firefox, Apple Mail, and Word (for example) all running at the same time. I'm selling it because I bought a lighter laptop for travel.
