for me the main reason is latency... with software based emulation you get at 
least one frame of latency, often even two. i find playing fast paced games on 
emulators quite annoying because of this, especially if you are still using 
the real thing the difference is quite real. with fpga based implementations 
you can get rid of this completely, and it works 100% like the real thing. 
(minus the fact that even the so called modern display itself may introduce 
latency, but thats another problem)
