German custom car shop Mattes-Interieurtechnik has customized a Mercedes-Benz CLS-Class with leather-trimmed 17" iMac G5 complete with wireless keyboard and mouse. Although the iMac G5 is out of date with the arrival of the new Intel-based iMac, it is still one hell of a machine to be fitted in the back of your car.
Too bad they don't customize american cars otherwise I would've asked for a custom made Mac Pro with 30" flat screen in the back of my TB! (yeah, right.) =P
