Don't you mean Taking it Back.. Bringing is speaking from the position of Best Buy. Or you have already made your mind up and your speaking as if you had already done it, so complete the task at this point perhaps.
All I can say, you "impulse bought the iPad" had you thought more about it before hand perhaps you would not have made the purchase. Also, if you put that much leverage on what others say and not what your own conscious is telling you, then you need to make a more informed decision on whether this is a device that suits your desires wants or needs at this moment in time.
Too many people today make uninformed decisions based mainly on Impulse or Immediate Gratification. A Little delayed gratification can go a long way and to practice it in the beginning is part of growing towards making less hasty decisions on the conscious part and being more clear in the mind to accept the rewards later when it all makes sense and agrees with your current situation or surroundings.
Making haste is to make waste. - When in doubt, wait it out.
Get to a quiet place, then think to yourself without speaking aloud, Is this what I want, your mind will answer you will feel or sense what is right. You probably already had that answer before the purchase was made, but you seem to have done it anyway, but at that moment your mind was probably making you feel the regret your now communicating to this very forum.
That is a step in the right direction, now just as you acted on the want, now act on the thought or feeling your subconscious is already knowing, only you have to hear it first. No one else can tell you whats right for you, advice will be there always but the choice is yours in the end.
