Working with a tablet is faster and more efficient than with a mouse. The hand can travel from point to point on the screen in a single movement instead of repeated slides, as with a conventional mouse. It also allows more natural input for activities such as drawing and photo retouching. Having pressure sensitivity is very handy and most graphic programs can benefit from this input. Touching the tip of the finger on the tablet surface is the equivalent of a click, and the pressure can be used to vary stroke width, opacity, effect intensity, and other attributes. If one chooses to buy a graphic tablet, invest in a Wacom model. There are some cheaper alternatives, but none of them has the same ubiquitous driver support, software integration, precision, and reliability as Wacom. No wonder they have over 85% of market share. Holding a pen is also much more ergonomic than using a mouse, and most users with repetitive strain injury (RSI) or tendonitis suffer less pain when using a tablet. Working with a mouse requires repetitive muscle movements while the rest of the hand keeps still, creating uneven muscle fatigue. A pen, on the other hand, allows working in a more relaxed position and eliminates the forearm twisting that strains muscles and tendons. At the end of the day, it feels much more natural and relaxed. Wacom pens use patented electromagnetic resonance technology, so they don't need batteries or any wires to function, reducing maintenance and weight for a more natural pen feel. The Wacom tablet is indeed a must for every designer or a person with a disability, who can utilize and maximize the complete use of the Wacom tablets have to offer, the sheer power, endurance and ergonomity will ensure that the user stays comfy while doing the job!
