Almost all tablets use a touch screen, which works by detecting taps and gestures. While these screens are capable of detecting a wide range of inputs, virtual keyboards lack the precision, and often the size, of physical keyboards. This imprecision, coupled with the lack of tactile feedback, makes a touch screen slower to type on.

Similarly, touch screens typically lack the resolution of cursor-based input devices. Even though touch screen technology regularly improves, fingers are far larger that the point of a cursor on a screen, making fine inputs difficult to detect on tablets. Styluses, which are supported on some tablets, offer better precision but require two-handed operation. Most tablets support keyboards and input devices, which brings them on par with laptops but sacrifices their portability and low weight. Some tablets come with custom-designed input devices and are sold as "convertible" devices.

The slate-like design of tablets and designers' emphasis on thin-form factors also limits their volume. Tablets typically have less RAM, storage space and processing power when compared to laptops.
