They sell refurbished products that old in Apple stores? Never knew that 
It's not an official Apple store; it's basically a computer repair shop that specializes in fixing up old Apple computers (they are an Apple authorized reseller) and sells them at discounted prices, although they do offer several newer models as well. They even had an iMac G5, a PowerBook G4 and several Power Mac G4 towers on display there as well.
Even though this MacBook is "old", it runs and looks almost as if it were new. There are no major defects in the case and no discoloration at all (which was pretty common in these models), and with the RAM maxed out at 2 GB, it runs OS X Snow Leopard quite satisfactorily.

Depending on what I'm doing, I can easily get at least 2 and a half hours of battery life, which is nice.
