GPGPUs have been a lot more interesting with the rapid pace of development in recent years, but there are still software optimizations that are only feasible on an FPGA. They're one of the most interesting pieces of hardware a programmer can use to develop high-performance hacks. When I worked at Cray, our team found numerous ways to make them useful. I've been meaning to pick one up for a long time.
