The major difference between Uno and Leonardo is that Leonardo has an ATmega32u4 which has support for the USB, whereas the UNO has ATmega328 which doesn't have the USB support onboard. ... Whereas the UNO requires an additional microcontroller to provide the USB capability. Cost wise Leonardo is cheaper than UNO by 20%

The Arduino Leonardo is a Microcontroller board based on the ATmega32u4. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

The Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.
