I get the appeal of having both in one, trust me. But having a better phone and a better tablet for the same price seems like too good of a value to pass up in comparison.
With that said, if the trade-in deals are really good I'll give it another look.
Yeah I don't disagree with your reasoning at all, but I look at it the opposite way where the convenience is more important. Don't get me wrong, it's exorbitant any way you look at it. But having a tablet fold into my pocket is something I've been waiting for a long time to come true. I haven't been this excited since the first iPad and the first Samsung windows tablet. The tech, durability, pricing, etc may not be here today, but there is no doubt that this is a complete game changer.
