"If not tech savvy", that made me laugh, Cold Storage regardless of device doesn't have to be difficult. But to say Jade is for the non technical is funny. @adam3us is more technical than 99% of the Bitcoiners on here and put out an incredible product. (Not enough for me to wear around my neck but I understand how completely secure it is once it has been used ONCE to get onto the Bitcoin Base Layer.) 

 Coldcard requires more of the user.  A non-savvy user could easily permanently brick a coldcard.
