I have had the Samsung Galaxy S4 for less than a week now (awesome device!). I could have bought the new Samsung Galaxy Note 8 for around the same price but after picking it up I thought no way!
I can hardly stand my car keys in my pocket. The S4 will be hard enough for me to accept. That thing... no way!!!
It is pretty cool and I would like to have it for the novelty factor. But that's about it.
