Apple's iPad 2

Apple's iPad 2 is thinner, lighter, faster and more full-featured, and incorporates enough changes and updates to maintain Apple's strong sales in the tablet market. The iPad 2 looks a lot like its predecessor, with a few important tweaks, like front- and rear-facing cameras. The new model weighs in at just over 1.3 lbs. That's about 3 oz. lighter than last year's version, and while a few ounces may not sound like much, every bit of weight that can be shaved off a tablet matters. The iPad 2 also features a 33% thinner aluminum shell with a flat back and beveled corners wrapping around the 9.7-in. screen. Despite early speculation that the new iPad would have a higher-resolution screen, the display specs haven't changed; the resolution remains 1024 by 768 pixels, with 132 pixels per inch. This is a device that has redefined how people use computers, and its reach is not limited to just consumers. Companies are rolling out iPads instead of more expensive laptops; healthcare facilities are using them. So are law offices and financial firms. In less than a year, it has found a home in the workplace.
