Worth mentioning- it IS C. All the Arduino environment does is provide a super-simple front end to the AVR-GCC port and a super-simple front end to the STK500 protocol for bootloading code. A knowledgeable user can completely ignore the Arduino libraries and just use the UI. A knowledgeable user can also easily expand the device support to any target processor support by AVR-GCC, which is to say, pretty much all the ATMega and ATTiny parts. Heck, a knowledgeable user can ignore the IDE entirely and treat the board as what it is: a well-documented extremely versatile open-source development board with a staggering array of daughter boards.
