Cold storage is still too technical and whilst the trezor sounds good, I am not so sure it will go mainstream. I think it needs to be shrunk down to a size that you can fit in to your wallet. Its a bit like the cell phones of the 80s for now, but a great breakthrough non the less.
If tescos and its foreign equivalants would integrate such a device in to their club cards then mass adoption will follow for sure. Its all very plausible to me. Time will tell.
I predict 2016 for $16666.66/BTC. Forever the optimist
