The FPGA is in a very exciting phase in its development, so it's hard not to get hyped.
Depending upon which arcade boards get implemented on it, I may end up scrounging up the cash for one.
I'm excited for Natami as well, but it seems like it will be well out of my price range, and I'm not sure if the additional muscle will really matter much to me.
The most powerful Amiga I've owned personally is a modestly expanded A500, after all.
