Touchscreen Sensitivity

Before you buy a tablet, you should play with one in the store and check to see how sensitive the screen is to your touch. You may find that some screens are really sensitive, and some require a stylus or fingernail to react to your touch.

There are two basic technologies used for most tablets, resistive and capacitive touchscreens. In general, resistive touchscreens are more accurate, but usually require a stylus or fingernail and a small amount of physical pressure. Capacitive touchscreens respond very well to bare fingers, a metallic stylus, or any other conductive object, but they can't be used with non-conductive gloves.

The rationale for using a resistive touchscreen in Android is in devices that are intended primarily as e-book readers. The less responsive screen makes it harder to accidentally turn pages while reading. If you're looking for an all-purpose tablet, your best bet is to stick with capacitive touchscreens.
