Samsung Galaxy S - crappyest clicky plastic retarded phone i ever held, But you can play games on it, regardless that it feals cheap in your hand considering your payment on it, its a good phone decent battery and a over saturated display but with a good powerhouse behind it
Dont consider that sgs 3 will be any different except performance change it will be the same crappy clicky plastic, considering there developement ideeas expressed ant the world mobile congress an i quote "we are working at makeing our phones thiner and lighter" (cheaper plastic then so far its gonna melt :) )
BTW: the iphone 5 video will be fake, microsoft and google has done smilar videos about there os, infact android was the first to introduce the concept of virtual keyboard and hologramic progection of indication keyboard when dell stated building phones with there os
Rest assure that none of these platforms will posses this capability in the near future
