现在是2009年。个人使用的主要是便携式计算机;同10年前的笔记本式计算机相比,这种计算机又轻又薄。个人电脑的尺寸和形状多种多样,通常内置于服装和珠宝上,例如手表、戒指、耳环和其他随身饰物。具有高分辨率视频接口的计算机可以小到戒指、别针、信用卡,或者大到一本薄薄的书。 It is now 2009. Personal use is primarily a portable computer; it is lighter and thinner than a notebook computer 10 years ago. Personal computers come in a variety of sizes and shapes and are often built into clothing and jewelry, such as watches, rings, earrings, and other personal accessories. Computers with high-resolution video interfaces can be as small as rings, pins, credit cards, or as large as a thin book.
