Tablet Computer Variety Uses

A tablet computer, or a tablet, is a mobile computer, larger than a mobile phone or personal digital assistant, integrated into a flat touch screen and primarily operated by touching the screen rather than using a physical keyboard. It often uses an onscreen virtual keyboard, a passive stylus pen, or a digital pen.


The term may also apply to a variety of form factors that differ in position of the screen with respect to a keyboard. The standard form is called slate, which does not have an integrated keyboard but may be connected to one with a wireless link or a USB port. Convertible notebook computers have an integrated keyboard that can be hidden by a swivel joint or slide joint, exposing only the screen for touch operation. Hybrids have a detachable keyboard so that the touch screen can be used as a stand-alone tablet. Booklets include two touch screens, and can be used as a notebook by displaying a virtual keyboard in one of them.
  

A Tablet PC is a portable computing device which looks much like a detached screen from a conventional notebook computer, or perhaps a hand-held computer that's been scaled up. 
   
As a quasi-hybrid of laptop and palmtop computers, the Tablet PC owes much to those earlier technologies. However, one of the key advances that made the Tablet PC possible is the development of ultra-low power microprocessor chips by companies such as Transmeta and Intel. Another standard feature of the Tablet PC, handwriting recognition, first made its appearance in the Apple Newton palmtop computer. 


 
Unlike a notebook (but like a palmtop) the normal way of entering data in a Tablet PC is with a stylus rather than a keyboard. While most models do offer keyboards (integrated in the so-called "convertible" models and separate in the so-called "slate" models), the Tablet PC is designed to use the stylus for most routine tasks. The Tablet PC generally offers some kind of handwriting recognition, and uses modified versions of popular applications that are designed for stylus input. The user interacts with the computer by drawing directly on the screen with the stylus.



Advanced tablet technology now means that millions of new users are discovering the thrill of interactive gaming with high definition graphics, quality audio and interactive screens that respond instantly to the lightest touch.

 
It's reasonable to assume that Tablet PCs will become lighter, more powerful, and less expensive as time goes on. It may be, however, that the real usability gains come through integration. The integrated features that are now available in cell phones (such as digital cameras) would seem to be ideal for adding into the Tablet PC, since they operate under similar constraints of size and power consumption.  Perhaps the cell phone itself could be integrated.
