Do you think constant Firmware upgrades on hardware wallets are their weakness? I have gone through some firmware upgrades for some hardware wallets (Ledger) and I have to say for someone with good technical knowledge, it was not a good experience. 
The normal handling of the hardware wallet and the software is not that technical, but still a daunting task for people that are not that technical. (Thinking about the transition from the Ledger browser plugin for Chrome ..to the Ledger App)
What can be done to improve the firmware upgrade for these devices ...to make it "Idiot Proof" ? What happens when Ledger or any hardware manufacturer goes bankrupt and exploits are found and the developers are not there to plug the holes? (Export seed to Electrum?)
