Ereaders are so last year. Tablets were the watchword at this year's annual Consumer Electronics Show (CES) in Las Vegas, January 6-9. This year, the show set new records, with some 2700 companies from around the world exhibiting at the multiple exhibition halls and 30,000 attendees gawking at the products. What did they see? There were still some 3-D televisions on display--a popular technology at last year's gathering--and small crowds formed to watch people use Microsoft's recently released Kinect game system. But tablets were definitely the star of the show, as companies large and small rolled out their iPad rivals. Among the many tablets at CES, a few stood out. Samsung's Galaxy Tab, which uses an Android operating system, was officially released late last year as one of the first iPad competitors out of the gate. For those interested in ereading, it offers the wide range of ereader-app options available to Android users, including OverDrive's app to allow library ebook and audiobook lending. Another highly promoted tablet, Motorola's upcoming Xoom, is also Android-based, making it likely to work with the OverDrive app as well. One more impressive tablet: Research in Motion's BlackBerry PlayBook, which uses its own proprietary operating system, BlackBerry Tablet OS, and comes preinstalled with a Kobo ereader. Smaller and lighter than the iPad and other competitors, it can juggle multiple tasks seamlessly. It will be released in early 2011; if it catches on, it could be a contender--though library ebook lending options still have to be hashed out.
