And what happens when 'mytrezor.com'
is down for some reason? Can I still make
payments?
People from Electrum, Multibit, Armory and others are working on TREZOR integration. Once done you can use these clients to perform operations.
Ok, thanks. I wait a bit then before
moving significant amounts:-)
I have already moved "significant" amounts to my Trezor because if I cannot wait for the web site to come back up then, as a last resort, I can always just enter my seed into the adroid Wallet32 ap, wait for it to sync, and then send my BTC from there.
Also, I do not consider the Trezor to be one of my "everyday" wallets. In my mind it is my BTC "safe" used for longer term storage. If the web site is down for an hour or two, or even a day, that is not a big concern for me. And if it is down for and extended period of time I always have wallet32 as a backup.
