One recent survey of consumers found that the iPad is the most sought-after electronic device this holiday season. But you may want to think twice before buying one this month. The iPad was launched in April of this year, which leads most industry experts to assume that the next-generation iPad will be released around the same time in 2011. If that turns out to be true, it will presumably cause the older model to drop in price but provide consumers with a new model that could fix some of the iPad's shortcomings, notably the lack of a front-facing camera. Either way, a wait is wise.
