Teensy 2.0 USB MIDI, Disk, Joystick, RawHID & Flight Sim Controls. Optimized digitalWrite, digitalRead, pinMode, etc. 3.5K extra program memory (smaller bootloader) International (non-US) keyboard support. Small form factor. 3.3 volt option & Tools > CPU Speed menu. Works on Mac Leopard and Snow Leopard. Non-Serial USB (no driver install message on Windows). Uno reset emulation, Serial.print() in setup() works.

Arduino Leonardo 9V unregulated power input, for easier use of external power. USB vs 9V automatic power selection. Arduino shield form factor (check compatibility, some only support Arduino Uno). Hardware cloning is allowed.
