So I have a MBP coming in on Wednesday, but I was having second thoughts about getting the hi res anti glare over the hi res glossy. Anyway, would there be any problems with me exchanging it for the exact same model but with a different screen option? Can I open the box to play with it and then exchange it? I haven't been to the store to compare the two, I just ordered off impulse. I don't want this thread to turn into another AG vs. Glossy argument, I just want to know the answer to my question and don't want to wait until tomorrow to call in. Thank you!
