The ViewBook 730 has a 1GHz processor, which is average for tablets, but only 512MB of RAM, 8GB of internal memory (although the device does have a micro SD card slot through which users can expand the memory by up to 32GB) and a single front-facing camera for videoconferencing. Furthermore, some critics panned the 730's low-resolution screen (800 x 480 compared to most tablets' 1024 x 768) [Orqula]. However, the 730 does come with a stylus, which can be used to add notes or pictures to existing apps, e-books or documents. ViewSonic calls this technology RiteTouch -- it also works with a finger instead of the stylus [source: ViewSonic]. Like all of ViewSonic's tablets, the 730 has WiFi and Bluetooth capabilities.
The ViewPad 7, which came out in 2010, offers less in terms of power (with a 600MHz processor) and memory (only 512MB, though it also has an up-to-32GB micro SD card slot), but it does have front-facing (0.3-megapixel) and back-facing (3-megapixel) cameras [source: ViewSonic]. And in September 2011, The ViewPad 7 will be reincarnated: The company has slated an international release of the ViewPad 7x, which will have amped internal workings [source: Gupta].
The ViewPad 10pro's main feature is its dual operating systems: Android 2.3 (Gingerbread) and Windows 7 (the buyer's choice of either Home Premium or Professional). To handle that, it has 1.5GHz processor and 2GB of RAM, along with an open slot to add a memory card to the optional 16GB or 32GB of internal memory [source: Cooper]. It has a single, front-facing 1.3-megapixel camera, as does the ViewPad 10 [source: ViewSonic]. The ViewPad 10 also has similar stats when it comes to memory, storage space and processing speed, but lags when it comes to its dual OS: It uses Android 2.2 (Froyo) -- a mobile OS that was initially designed for smartphones, not tablets -- with Windows 7 Home or Professional [source: ViewSonic]. (See the next page for more about how these dual operating systems work.)
Last but not least, the gTablet has 512MB of RAM and 16GB of memory, plus one of those handy micro SD card slots for memory upgrades [source: Murph]. It boasts a 1GHz dual-core processor, which can handle multiple apps and future OS upgrades. The gTablet and the ViewPad 10pro both have an HDMI port -- which means that you can hook them to a high-definition television and view your tablet's content on a big screen with excellent clarity [source: ViewSonic].
A ViewSonic tablet's battery should last about eight to 10 hours. We'll delve further into the VeiwSonic tablets' accessories and features on the next page.
