What a controversial statement! Where am I going with this?
Quite simply a core reason I chose Android over an iPhone is the heavy handed practices of Apple in choosing to disallow Flash support and heavily monitoring all apps available on their devices (which translates to no classic game console/computer emulators). Since then the Android Market seems to be gradually digging up and rooting out emulators. First it was the N64oid and Ataroid by yongz that got the boot. Next, I can't find Atari800 via searches (even though it still seems to be there via direct link). Now it's...
SNES9x that is the target. The best part, however, if it Google has a problem with you they just say "there's a problem..." and you're screwed. There's nothing more than a vague explanation. I've read similar stories from people with AdSense accounts. Do you run a business revolving around AdSense income? Google can take it away in a flash with no explanantion or dialog. Quite frankly, Google is becoming a scary company to deal with that is too big for its own britches.
Now, I'll give you that I can still install .apk files on my own and other 'third party' markets currently compensate for this. And, at the very least, Google lets me run what I want to on my phone even if they don't directly approve of it. But the heavy handed policies of Apple apparently exist on the other side of the aisle as well moreso than we might like to think.
