Maybe, maybe not. It depends on the application and the user. We're seeing tablets advertised like crazy these days, and a trip to any busy coffee shop with free wi-fi will make it obvious that while there may not be as many tablets in use as notebooks, you see a lot more of them than you did five years ago, when it seemed like Bill Gates was the only person who had one, which he tried to show off as often as he could. In 2010, Apple debuted the iPad, and before long tablets were all over the place. So, on behalf of people we know -- and there are more than a few -- who either sneer at tablet computers or aren't sure they need one, we turned to David Needle, editor of TabTimes.com, for advice on what kind of tablet to buy -- assuming we need to buy one at all.
