One of the reasons I bought a smart phone after using a Nokia 3310 for years and years is to be able to watch shows and such on it (I travel a lot by train and such). I bought a 32 GB SD micro card for that reason. However, it still fills up pretty quickly. I am now debating whether or not I should buy a second card. Of course, there is little doubt that frequently changing the SD card would age the phone quicker. But is it something that is really bad and simply shouldn't be done period, or is the increase in wear and tear little enough to risk it for? Does anyone here have any experience with this?
