First job out of uni was writing device drivers for Motorola Symbian devices on H4 boards (I want to say LDDs and PDDs?). Codewarrior or carbide if you fancied a reboot every 2 mins, 40 minute turn-around times to flash and boot your software, boards without working SD and having to log to the screen ...I do not miss those days at all. BlackBerry was like a bloody dream.
