Like all things, it's a matter of saving if it's about money and a matter of patience if it's a hot new device. That isn't a knock against you, just my thoughts at the situation
I've seen early college students sell all they have for 5's and 5S's on their launch days and be forced to use the smallest memory see available, and for what? "If I don't get it now I'll never get it!"
Yes you will. Might be six months from now, but you aren't really losing anything being patient
Again, not anything against you. Just a random rant
