When a harried-looking man carrying a whining and crying young boy stops you and tells you that he needs an USB hub that can connect to an iPad2, do not ask him what an USB hub is. When he explains to you what one is, do not ask him why anybody would need one of those*. When he explains to you why, and you tell him that you have no idea what you could sell him, the act of the man then turning around and walking out of the store is an indication that there will be no sale today.
Do not follow him.
I hope that this feedback helps!
*Because I’d like to download video camera movies… well, hell, I’d just like to download video camera movies, period – which is apparently something that Apple doesn’t want me to do, ever. But assuming that I ever can, it’d be nice to do it without simultaneously draining battery power, yes?
