Four of us, kids are 14 and 15.
Five smartphones, two laptops, five iPads, four desktop computers (currently operational - another half a dozen in the basement in the state of who really knows), three working Kindles, two iPods (docked in alarm clocks), a netbook, a PS/2, 2 XBoxes, three Rokus, one google TV - and probably more than that, but that is what is in fairly regular use.
My husband spent years "in the industry" and I spent years in IT. Not all of those were paid for out of pocket.
