How to Compare Graphic Tablets
Graphic tablets typically consist of two devices: a sensitive flat surface and a stylus. Once connected to the computer, the stylus controls screen movements like a mouse, yet is used like a pencil. Tablets are available in a range of sizes with varying features.

Identification
-
Graphic tablets, unlike standalone touch devices such as the iPad or tablet PCs, must be connected to a computer and are not designed to be held. They come in a range of sizes, from small 6.2 inch to 3.9 inch models to extra large 19.2 inch x 12 inch devices. As you might expect, larger sizes have higher price tags.
Types
-
Tablets are available in a variety of brands. Wacom offers wireless and USB models, as well as tablets that respond to both touch and stylus input. Other brands, such as Genius, offer less expensive products. Some tablets come equipped with full or trial versions of graphical imaging software, such as Photoshop. The Wacom Cintiq is well regarded among design professionals.

Considerations
-
If you intend your tablet for artistic purposes, make sure you purchase a brand with high pressure sensitivity. Such tablets translate decreasing pressure as finer or less opaque lines, giving you a much wider range of creative possibilities. Wacom Intuos products offer high pressure sensitivity (2,048 levels for all sizes), while comparably-sized Genius models offer only 1,024 levels.
