When you buy a computer, you want it to last. And a Mac will. Thatís because a Mac is designed and built to be as reliable as it is beautiful. Itís made from strong, beautiful materials like aluminum and glass. It comes with the latest technology ó powerful processors, advanced graphics, and fast memory. And it has features you wonít find on a PC. So from the outside in, a Mac is designed to be a better computer. A Mac is designed for a long, productive life. Apple designers and engineers spend countless hours ensuring that each Mac is precisely built ó inside and out. From the down-to-the-micron fit of each internal component to the finish of the enclosure, every detail matters. Take MacBook Pro, for example. Its unibody enclosure is machined from a solid block of aluminum. The result is a MacBook Pro that is thin and light, looks polished and refined, and feels strong and durable. To make a better computer, only quality components and materials will do. Thatís why every Mac contains a hard drive, memory, graphics processor, even a power supply specifically chosen to give you the best performance possible. And materials like aluminum and glass (in iMac and MacBook Pro) or rugged polycarbonate (in MacBook) keep all those high-performance components safe and sound. Getting a few hours of battery life from a notebook is good. But for a Mac, good isnít good enough. On a single charge, you can get up to 8-9 hours on the 15- and 17-inch MacBook Pro, and up to 10 hours on the MacBook and 13-inch MacBook Pro. That means you can power through a day of work or a day of classes without stopping to find the nearest outlet. And the battery inside MacBook and MacBook Pro can be recharged up to 1000 times ó good for about five years of typical usage ó and lasts nearly three times the lifespan of typical notebook batteries.
