I would love to see Smart Stay and S Voice working on say the Galaxy S II. Hopefully Samsung wont be jerks like Apple was and make those features exclusive to the Galaxy S III
I have a same feeling too. However with the help of xda devs. we might actually see at least the Smart stay. Android OS is move versatile than iOS I don't think it will be that challenging to port it. The S Voice on the other hand might be complicated as it requires connection to Samsung servers like SiriI dont think they will allow it except on the s3, these new features make the phone stand out from the previous one... same reason why siri is not on the iphone 4 and only 4s to get you to buy the incremental upgrade..
