That was a joke (yes, I know, my sense of humour is nothing to write ome about). Your camera would work just as fine with microSD in a SD adapter, just as any other SD device. The only investment here to protect are your existing SD cards. Anything else, and it's back to why a SD investment should be protected and not a, say, CF one (in which you could stick SD anyway). One could also argue that two slots add additional functionality that you would not have otherwise, regardless of the card format (like my personal 2 micro over 1 SD preference). But the topic has been beaten to death and the only consensus here is that there is no consensus, no matter what the RX51 choice is/will be, someone will be disappointed. No further replies on my part.
