I don't have one, but it seemed to be fairly well-received. Supposedly zero lag. Don't remember if it supports savestates.
If memory serves, the Minis all suffer from some degree of audio lag, not sure about input lag. For me, perceptible lag is kind of a fun-killer, and even input lag that I don't consciously perceive has an effect on my play, ergo an effect on my enjoyment.
As for game anthologies on newer consoles? Not really my thing.
Analogue Mega-SG is the best way to play Sega Genesis outside of original hardware. Zero Lag, works with the original Sega CD machines, Free Master System adapter, original controllers, etc. I absolutely love mine. With a jailbreak, you can also play Colecovision.
