It seems to be a status thing anymore… and stupid one at that IMHO… get yourself an iPad mini with cell capabilities if you need a massive screen device that fits into no ones pockets - iPhone - its a mobile telephone that gives you some conveniences and access to what normally would only be a computer accessible function.
I don't know if I'd go bigger, I'd certainly consider it though. iPad mini is nice, I've looked at them but they need pro motion and phone capabilities for me to really consider it.
