While the iPad 2 remains the most popular tablet computer available, consumers with particular interests who don’t want to spend $500 or more on a new device now have compelling alternatives to consider.
Whether you are an avid book reader looking for additional interactivity and features on your e-reader, a business user who wants to securely access a corporate IT system, or an iconoclast who doesn’t like the iPad’s one-size-fits all hardware and operating system, there is no greater time than now to explore tablet alternatives.
Any of these options deserve a place on your holiday shopping list.
Amazon Kindle Fire and B&N NOOK (Price conscious/avid readers)
