I'm a college student majoring in Electrical and Computer Engineering. I do most of my work with microcontrollers, PIC32 devices most recently. I have a lot of my work up on my blog www.tahmidmc.blogspot.com
I'm using the Edison as part of my project team (robotics applications). For now I'm just learning to use it in general - just got used to Linux really.
Between software and hardware design, I'd say I'm more of a hardware design guy, but I do my fair share of programming on microcontrollers.
