As great as cold card is...this is kinda dumb. Obviously the solution they were looking for with this was geo-dispersed multi-sig

I fail to see why this is. It is less daunting than multi-sig

What's daunting about multi-sig?

seed xor is like raid zero.

if you lose one seed you lose everything and you now double your chances of losing your data

No, you can still use the original seed.. some people use xor just to create new wallets from their seed, because you can always get those wallets from the original so you dont have to worry about writing down every seed for every wallet you have. As long as you save the original seed you are fine.
