I had bought two class 6 8gb cards for my TP2 at $13 each from Amazon. I wanted a 16gb card but the cheapest 16 gb class 6 was running about $65. I have at least 4 pouches that fit my TP2 but none have a pocket for an extra card. After brainstorming how I could sew a pocket on my case, it came to me. I have about 5 micro sd card adapters. Why not superglue one of them to the back of the pouch. It would be out of the way, and would be realy pratical. If glued facing upright, it would be nearly impossible for the card to fall out- as he card kind of click into palce. This way I could swap out a card at a moments notice; in my case I have the other card loaded with about 10 full lenght movies. Heck you could glue two cards, one on each side of the belt clip and have two spare slots. I would upload a pic if I knew how. Just an idea that I feel some might be able to use as I know many of us have left over cards from previous devices.
