The iPad Pro.
Hell, I even went as far as buying one at Target at 10% off, only to return it, unopened, a few days later.
I really want one, but to be truthful, I'm doing just fine with my iPad 3, and the $750 is, to be honest, better used elsewhere at the moment.
I did keep the Apple TV 4 I bought along with the iPad Pro as a consolation prize of sorts. $135, now that's an amount I could definitely afford to spend on a plaything for now
EDIT: Didn't realize this is in the photos forum, so... uh... behold the stock photo of an iPad Pro!
