Even apart from nostalgia, there's very solid arguments to be made for actual hardware music gear, no matter how space-convenient a DAW is. Plenty of emulators don't do more than loosely approximate the sounds of hardware synths (and the SID filter in particular has never been emulated more than approximately,) and even with the Amiga UAE just doesn't quite have the same tone to it as the real thing.
An fpga SID can emulate everything well except the filters. A SID is very small in fpga and doesn't require DMA for it's looped "synthesizing". There was a recent discussion about adding SID capabilities to an enhanced Paula in fpga for this reason. I would bet money that someone has already had a Paula and SID in the same fpga before too. How good an fpga could make it sound, I don't know. It probably would sound different but hopefully better than software emulation. There are 2 different versions of the SID too. Most people prefer the early one with more distortion over the later bug fixed version with cleaner sound.
