With a fast 2.4GHz Intel Core 2 Duo processor, MacBook breezes through everyday tasks such as emailing, web browsing, and working with documents, spreadsheets, and presentations in iWork or Microsoft Office for Mac (sold separately). It also provides plenty of horsepower for more processor-intensive activities such as retouching a photo in iPhoto, editing an iMovie project, and composing a new song using GarageBand, so you can make the most of the included iLife suite of applications. It even runs Microsoft Windows at native speeds. Better still, MacBook comes standard with 2GB of memory (with support for up to 4GB), so you can run multiple applications smoothly and efficiently.
