Not sure thin is a big deal anymore; at least half of the smartphones I see around me are in some kind of case that makes it a good deal thicker -- I use the "replaces the back" type flip cover which actually adds more thickness on the Note 3 than it did on the note 2 (or does on my Moto G travel phone) and actually find the heavier back on the flip cover an improvement over the thin faux-leather the Note 3 came with out of the box.
