Tablet PCs are the latest computing technology that is available to consumers and some models cost under $200. Most tablets have a 7 to 10 inch screen and they typically have features such as a front and rear facing camera, the ability to download apps, can record and playback movies and are designed for high end games. They typically have between 2GB and 16GB of RAM and have a memory card that can hold up to 32GB of data. Most tablets can be converted into different types of portable computing devices which include GPS devices, credit card scanners and security screeners. Lower end tablets typically do not have the ability to be utilized in this manner.
