Okay so I've decided to buy a mac mini for a family member for xmas. My only concern is that they may release a much faster mac mini for the same price at macworld. So here's the thing, according to the apple rep, all apple products purchased this time of year can be returned 14 days from xmas day, as opposed to 14 days from the purchase date. The macworld keynote is 13 days after xmas (jan. 6th). So, could I buy it now, then return it on the 6th (if unopened) if they reveal a new one at macworld? Or do that specifically prohibit returns when an upgrade of the product has just been announced?
