As a current Thunderbolt owner who is desperate for an upgrade, my only concern is the 16GB and the lack of a Micro SD. Unrooted, the usable space is somewhere north of 11GB after all is said and done. I can probably do some paring down of my apps that I don't use regularly and don't see myself downloading full HD movies, but photos and songs may become an issue a year or so from now. If this thing had 32GB or a Micro SD slot, I would have pre-ordered already. Anyone else hesitant?
