There are only two programs I use on Windows. One is Tower Hobbies "Real
Flight" RC airplane flight simulator. The other is "AVR Studio" a
programming suite used in programming Atmel's AVR 8-bit microcontrollers.
They have one, a relative new one, for the 32-bit controllers but the 8-bit
AVR's are only supported by a Windows program. If it wasn't for that . . .
