How to choose the best Wacom pen tablet for your needs
Why use a pen tablet instead of a mouse
Working with a tablet is faster and more efficient than with a mouse. Your 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 pen on the tablet surface is the equivalent of a click, and the pressure (plus tilt, in more feature-rich models) can be used to vary stroke width, opacity, effect intensity, and other attributes. There are two buttons on the pen and either can be programmed for right click.
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. In my personal case, it completely cured a chronic pain I had in my right wrist. 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 you to work 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.
Areas in which tablets dont work so well
There are a few areas in which tablets are not the ideal input devices.
Most games dont work very well with pen input, as their interfaces were originally designed for mouse control. Think about controlling a first person shooter with a pen. It definitely makes little sense.
In the architectural and engineering fields, theres a split: some users love it, some hate it, mostly because the mouse scroll wheel is very handy for zooming in and out on programs like Autodesk AutoCAD and Wacom tablets have that feature on the tablet surface, requiring putting the pen aside to use it. Pressure sensitivity is also ignored in those programs, neglecting one of the tablets main features. On the other hand, the more ergonomic position could more than make up for it.
Will touch devices kill pen tablets?
I doubt it. Without a major exercise in user interface design, my feeling is that we wont be able to achieve the necessary drawing precision with bare fingers to replace tablets. The two technologies are complementary and were already seeing some new Wacom tablets, such as the Bamboo Create, incorporate touch gestures. This gives us the best of both worlds: bare finger touch and gestures for quick window transitions, icon and menu selections, with a pen for more precise actions where pinpoint accuracy and especially pressure sensitivity are indispensable.
Which tablet should I get?
Go Wacom, ignore the others
If you choose 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. Wacom pens use patented electromagnetic resonance technology, so they dont need batteries or any wires to function, reducing maintenance and weight for a more natural pen feel.
Tablet size and resolution vs. screen size
Tablet sizes should be relative to your screen size and resolution. The smaller the tablet surface, the less hand movement will be necessary to move the cursor on the screen. Having a tablet too small for your screen leads to a jumpy cursor and makes fine selections too difficult. A tablet too big for your screen feels slow, requiring too much hand movement, and your muscles may tire more quickly.
Tablet resolution is also a factor. Wacom has two lines of tablets, Bamboo and Intuos. The former has half the resolution of the flagship Intuos4 line and this difference may be very noticeable, depending on your screen size. Given the same tablet size, the higher the resolution, the bigger the screen that can be used comfortably with it.
Bigger tablets, such as the 8" x 12.8" models, are difficult to use along with a keyboard and tend to be more adequate for single task work where typing is secondary, for example video editing or drawing. If you are an illustrator and you are used to drawing with very long strokes, a larger drawing area may be necessary.
For dual display use, keep in mind that the overall screen proportion is much more horizontal than the tablet itself. Through the system preferences configuration panel, the tablet can be set up for different screen mappings, single screen mode or screen switching with a hotkey. The most natural way, in my opinion, is to keep the screen proportion exactly the same as the tablet surface. If you use dual displays, this means that some of the vertical area of the tablet would be inactive and that the horizontal resolution available will be mapped to a much bigger number of pixelsfor example, 3840 x 1080 for dual 24" displays. This would require a larger drawing area than a single screen, and preferably a high end tablet such as the Intuos4 Large model. An alternative that works fairly well is to use a smaller tablet and set up a hot key combination to switch the control between the two screens.
My favorite keyboard for use along with a Wacom tablet is the Apple Wireless Keyboard. Because it has no numerical keypad it has a smaller footprint and fits nicely at either side of the tablet. A full size keyboard may be too large to be used on the side of a tablet larger than an Intuos4 Medium, leaving the tablet too far from the central seating position. Some users prefer to place the keyboard in front of the tablet. This position only works if you dont need to type much during the day.
Display resolution vs. Wacom tablet size
First days with your new tablet
Working with a tablet is a paradigm change and may require an adaptation period for hardcore mouse addicts.
All tablets work with absolute positioning, while mice are relative positioning devices. This means that you can slide your mouse several times to move the cursor across your screen, while on a tablet all you do is move your hand and position the pen tip on the corresponding point on the tablet surface.
This changes your eye vs. hand coordination logic and can be a little difficult the first time. In my case, I bought my first Wacom Graphire 4" x 5" model (replaced by the Bamboo line) after suffering from carpal tunnel syndrome for a good time. No matter what treatment or medicine I used, I always felt pain after using my mouse for extended periods, so adapting to a new input device was surely less painful than keeping the mouse.
My tablet arrived in the middle of a book design job and I delved straight into it, leaving the mouse disconnected. You can use a mouse along with the tablet, if you prefer, and Wacom also offers optional wireless mice that work on the tablet surface. But my reasoning was that the more I forced myself to get used to the tablet, the faster Id master it. After two days of work, I was already comfortable with it and never used a mouse again in the 12 years after that day.
