There is no comparison between the S4 and S2 comparing build quality and Sealed system. The S4 is a VERY well built, solid machine with a totally sealed system. I hope the new replacement for the S4 will have the same quality as the present S4 and not the S2.
Well as the owner of the new S6 which is the replacement for the S4, have a look at this German video on You Tube. You don't need to understand the German language to see what the poster has done - they compared the S6 to the S5 and the S6 seems okay until he/she hits a screwdriver off the side. (The music is fab though : ) )
