1)Bad news. So why are they selling a brand you laptop without it having USB3 support? I don't know what to say...Really, like any thing I can do? I heard that there are cables with 2 USB2 -> 1 USB3, is there anything like that?
3)No, not for gaming. But I don't want it to slow me down for no reason. And btw is it replacable?
4)Maybe 256GB or 128GB... or (as ur saying there are two places) maybe 2 128GB
