I liked it, but still too long. Cut out the bit about the IR blaster (save for a later commercial), cut out S-Beam (ffs I don't think we'll ever see a GS commercial w/o this), and cut out some of the useless jokes (b/c we get it already: old people are not bright, not so bright people buy iPhone, iPhone is for old people). If I didn't know anything about the phone, I'd think it was too cluttered of a commercial.
I wonder what the kid will do after he's done eating, I bet his hands are gonna be really greasy to pick up his GS4 ;-)
Also, I didn't know the GS4 wakes up the device after receiving a text/notification! It has always bugged me that Android devices don't do give you this option.
