Tablet computers are all the rage and aren't showing signs of going away. Many tablets have touch-screens, which include virtual keyboards. Other tablets have expansion slots for additional data storage or USB ports to attach external computer accessories like printers or external keyboards. The Google Android Operating System is the most common system used on tablets, with the Apple iOS powering the popular iPad tablets. Users can download and install applications, called “apps,” in hundreds of categories including games, language, cooking, and travel. Many apps are free, while some require payment. Most tablets connect wirelessly to computer networks or the Internet via Wi-Fi or mobile wireless 3G or 4G networks. A data plan contract with a wireless phone carrier, or a month-by-month plan is required for the latter. If you’re looking for tablets from Apple, Samsung, Asus, or other well known manufacturers you can bet that Kelkoo will have all of the most popular makes and models at the lowest prices on the ‘net!
