Yes, Trezor support would be amazing!
It's gotten to a point where one stake or supernode is worth several hundred thousand dollars. Hardware wallet support is a pressing issue.
At this point, NEM should use community funds to develop its own hardware wallet.
No, it's good to use Community Funds to develop integration in existing Hardwallet. Everyone who already has one doesn't want to buy a new one just for NEM.
Exactly. And existing HW wallet Trezor is outstanding so it's waste of time and money to develop new one. I contacted the vendor support and they told me, that NEM developers should initiate the integration and contact them and then a possible cooperation from their side can start. So they seem to be open to support NEM and any other coin. Actually, they already support bunch of altcoins but unforunately not XEM. Maybe someone from NEM dev team already started some work there but I'm not familiar with that.
