If you are making up your mind to buy a new desktop or laptop pc, it is not a new topic today. As the prices are down, many more features are available as compared to the PC's available before and more affordable models that offer power, mobility, and a long-life battery in a package. One alternative that is available is Tablet PC which has the size of a letter-sized notepad, pen activated screen, which is simpler to use at meetings and while traveling, and many more features that put them on par with relatively powerful laptops. It was launched in 2002 in an attempt to popularize pen-based computing and gradually gained attention as a useful tool for businessmen and educators. These machines are now in their second and third generation. The market for tablet PC's is in a boom and as most of the big players in the market have decided to jump on this bandwagon, it is predicted that the trend is likely to gain further momentum.
