Arduino Micro is very similar to Leonardo. The biggest difference between Micro and Leonardo, perhaps, is the form factor. Apart from the differences mentioned in the above table, one other major difference that I'd like to highlight −

Micro's ATmega32u4 has in-built USB communication, thereby eliminating the need for a USB to UART converter. This opens up several possibilities. Several of them are highlighted here.One interesting possibility it opens up is allowing us to use the Leonardo as a Keyboard or a Mouse, other than a COM Port.
