The sleek MacBook cuts a slim profile on any desk (or in any backpack or briefcase). It features a seamless, durable unibody enclosure with rounded contours that make it easy to pick up and slide into and out of your bag. It's made of rugged polycarbonate that withstands the rough and tumble of everyday life at school, at work, or while traveling. And since the bottom of the MacBook is covered in a nonslip material, it always stays right where you put it - whether it's on a desk, table, or airplane tray. MacBook portability doesn't happen at the expense of key features. The keyboard is full size, with keys that are curved to contain your fingers and highly responsive to your touch. Its low-profile design integrates perfectly into the unibody enclosure, so you'll get a comfortable experience whether you're typing a quick email or writing a lengthy research report. The connections and ports on MacBook are all smartly integrated on the same side of the notebook. So your cables stay neatly organized, and connecting and disconnecting your devices is easy and convenient. MacBook is as well designed on the inside as on the outside. Turn it over and you'll notice a seamless, sturdy, single-piece bottom case with no battery compartment. That's because the lithium-polymer battery is strategically built right into the enclosure. In addition to providing extra overall durability, this integrated design eliminates the space-consuming parts required by a removable battery. This allows more room for a larger-capacity battery and provides an even longer battery life - all in an enclosure that is thin and light. When you remove the bottom case, you'll discover a clean, simple interior layout that makes it easy to add more memory or a larger hard drive. With a fast Intel Core 2 Duo processor, MacBook breezes through everyday tasks such as emailing, web browsing, and working with documents, spreadsheets, and presentations. The LED-backlit 13.3-inch glossy widescreen display delivers stunning colors and instant full-screen brightness the moment you open the lid. And its 1280-by-800-pixel resolution offers an outstanding balance of luminous color and easy readability in a perfectly portable size
