A tablet personal computer (tablet PC) is a portable personal computer equipped with a touchscreen as a primary input device and designed to be operated and owned by an individual. The term was made popular as a concept presented by Microsoft in 2001, but tablet PCs now refer to any tablet-sized personal computer, even if its not using Windows but another PC operating system. Tablets may use virtual keyboards and handwriting recognition for text input through the touchscreen. All tablet personal computers have a wireless adapter for Internet and local network connection. Software applications for tablet PCs include office suites, web browsers, games and a variety of applications. However, since portable computer hardware components are low powered, demanding PC applications may not provide an ideal experience to the user. Everyday every mobile and PC company is announcing the launch of their Tablets. Currently if we look and find out then we would find Blackberry Playbook, Apple iPad, Samsung Galaxy Tab and Dell Streak. Each one of them has some exclusive and nice features but we get confused if we have to buy one. Everyday I come across a question- which tablet PC is best? Which one i should buy ? Which one have more features ? So I decided to do some research and tried to TABULATE THE TABLETS features..
