you have to admit that the preprietory features writen into Touch Wiz are the real draw here!
No, I don't have to admit that at all. I would have bought the S4, except I was turned off by all the Samsung software features, which I consider bloatware. Those "preprietory features" actually convinced me not to buy the phone. Now that Google has fixed that: great hardware without all the bloatware, I'm in.
