I wonder how much it costs! Maybe it is a way to get Bitcoin spread around the world! It is user friendly and enhanced security!
It's 399$. It has only 128 GB SD card, I don't think that's enough to store full blockchain. You'll need to change SD card 2-3 years later eventually.
Currently the full blockchain is only about 30G! How isn't 128 G SD card enough? Why do you need to change SD card just 2-3 years?
The bitcoin Blockchain will continue to increase its size so there will be a need to change your disk to another one with bigger capacity.
Assuming Bitcoin never increases its blockchain data limit, the blockchain could still reach over a TB in the years to come.
