bcarlton0, what area of business are you in? I'm a young engineer working with FPGAs in the medical space and I'd love to hear about what else is out there.
Ductapemaster, I have done designs in networking (e.g. packet processing and 10 Gb Ethernet), wireless (e.g. baseband part of a modem), glue logic, and other more specialized areas. FPGAs have a wide variety of uses other than ASIC prototyping and small glue logic.
