Well I had one a couple of months ago I had just gotten my new phone and it was really annoying that it had little to no memory (it was a crappy phone) my mum then suggested that I use the memory card in her phone I then took out the card and simply stared in amazement at it I originally thought it was gonna be fairly sizable but all it was, was some tiny paper thin chip that I had to be super careful with to avoid breaking it put all the technological advances of the past couple of years into perspective and whenever I think about it,it still impresses me.
