Ya... Cause a company the size of Samsung is going to come out and say "We use plastic because its cheaper." Even if it isn't the ONLY reason, you can bet your bottom dollar that it is a big reason. If the S4 already costs more to make than the One (which I haven't read anywhere, but I'll take whoever said it's word), it would cost that much more if it were made of aluminum. Anyway, the point of this thread is that the part number for the Snapdragon 600 chip in the GS4 is not the same part number that every other phone with the 600 has had. Somthing is different. Whether or not you like the rest of of the review doesn't change that fact. It merrits investigation. Maybe it is an improved version of the 600, maybe its an S4 Pro souped up to preform like a 600 and is only a 600 in name. Either way, it merrits investigation so people know what they are getting.
