I bought a class 6 16G RiDATA card for about $50.00 from NewEgg
http://www.newegg.com/Product/Produc...82E16820183245 back at the end of Dec and it has been working fine in my TP2 ever since.
I do think you have a point though about removing the card as to me these things are just to small to be heavy duty enough to be subjected to the man handling they might see in something that requires that which to me I would wager is the number one source of failures.
