But what if I have an SD based MP3 player, or an SD based thumb drive and want a larger then 2gb card? It just seems weird to limit storage of any device to something that based on normal growth will outlive the specification in such a short time. Sure, 2gb probably seemed quite large when the first 32 and 64 meg SD cards shipped in late 2000, but all they needed to do is look at the rapid growth of the hard drive capacity at the time to get an idea of how quickly the format might scale up.
