That simplicity is the point. A tablet is a computing device built around three physical realities: a flat touchscreen, a slim profile, and passive cooling. There is no mechanical keyboard, no hinge, and, in nearly all cases, no internal fan. This design imposes strict limits on performance and battery life, but it also creates a class of machine that is uniquely suited to specific kinds of work.

A tablet is not a laptop with a removable screen, and it is not a large phone. It is its own category of mobile computer, defined by its form factor and its operating system. The fastest way to understand a tablet is to see it as a machine optimized for direct manipulation and portability, not for sustained raw throughput. This distinction is not academic.
