Maybe it's a useful 3D Laser Printer to personalize Trezor(s).Imagine online gallery where user/customer can add name,logo etc...

Glad to see you guys updated myTrezor so that we can save account labels and transactions details.
Busy testing it out now.
EDIT: Everything seems to be working fine. Is there any plans to later include something like the Electrum Exchange Rate plugin where the fiat value of a transaction can be imported and shown and possibly where historical fiat values of transactions can be saved together with the transaction details?

have you guys noticed one can use trezor for ssh logins:
https://medium.com/@satoshilabs/trezor-firmware-1-3-4-enables-ssh-login-86a622d7e609#--respond.3l1zfhtk4
it's pretty neat, but it has some rather severe usability issues from my point of view (see my comment at the end of above article)

Yes, all hardware wallets override the signing code of the upper layers (here, the Electrum wallet), so malleability issues in the upper layer crypto library are not useful.
For more details, you can have a look at the plugin code @ https://github.com/spesmilo/electrum/blob/master/plugins/trezor.py - it's short enough and you don't need to dive deep into the wallet implementation itself to understand it.

Yes I know about 2.5.1 portable. That is not relevant, I still have a question for a Trezor developer: is Trezor actually signing a transaction LowS which overrides Electrum (or any other wallet that supports Trezor?) If so since there has not been a firmware update since the malleability issue it would seem the Trezor has always signed LowS. Still trying to wrap my head around how exactly Trezor works, the FAQ does not go into detail.
Agree, would be nice if one of the dev's can go into a bit more detail in a step by step way to explain exactly what happens from the time you initiate the transaction until such time as you broadcast it.
It seems so simple and quick when you do it but would be nice to know what is happening under the 'hood' so to speak.

Yes, I follow the Electrum threads. My question above still stands as I would like to clarify how Trezor works thanks.
Not sure if you have seen the latest update from Thomas. They have released a portable version for Electrum, version 2.5.1 and Trezor support is back in.
Tested it and all seems to be working fine. The account labels now also work, if you have multiple account. And the portable version is now again 'portable' i.e. it makes use of the data files in the folder from where its run.
You can download it from here: https://download.electrum.org/ just scroll down to almost right at the bottom for the portable version.

I have a question for one of the Trezor developers please. ThomasV posted that all versions of Electrum prior to 2.5.1 signed transactions HighS. He had to release a new version of Electrum to agree with the mandate for LowS in latest Bitcoin Core 0.11.1 to end the malleability attack by amaclin. If one tries to spend bitcoin from an earlier version of Electrum the send fails.
I can still use my Trezor with portable Electrum 2.3.2 no problem. Is Trezor actually signing a transaction LowS which overrides Electrum?

Not sure if you have seen in the Electrum thread, Thomas did post an update with a test version which supports Trezor again. Downloaded and tested it last night and it works fine with Trezor.

Interesting, up till now I thought that leaking single private key will reveal everything from that hierarchy DOWN, never up. Is this correct, or can really someone derive all private keys based on single private + xpub?
and maybe not have everything related to a single xpub key that can easily be leaked. Because if you lose xpub, everything is public, leak one private key and everything related to this xpub key is gone.
a little known fact, yes, yet possibly extremely costly to not understand it.
I follow one simple rule: never export a private key from a hd wallet. It stays with the hd wallet it came from, period.
The only legitimate complaint I have ever read about Trezor is that no fully validating node wallet supports Trezor yet.
Just run bitcoind, own electrum server and build electrum 2.5 from source. Easy.
Lol, but I obviously agree. I think the above way is the only way, but pretty difficult / time consuming / heavy on computer / etc
Hope to see an easier way soon 
Still fully love my trezor though, by far best way to store/use bitcoins. I'm really looking forward to purchasing a Trezor ASAP, it seems like the best solution for storing my bitcoins at this point.
Hardware / Cold-storage has been becoming increasingly interesting to me as my bitcoin stash continues to grow.

You will not regret purchasing a Trezor. The online user manual is one of the best I have ever seen. The only legitimate complaint I have ever read about Trezor is that no fully validating node wallet supports Trezor yet. But that is hardly the fault of SatoshiLabs and is an issue of privacy, not security. It would be cool to have an anodized aluminum case rather than plastic but that is esthetic not functional.

What we are working right now is to integrate TREZOR into multisig wallets such as Copay and this should be ready soon(tm).
Are you still having problems finding wallet developers that provide full node network access (for xpub privacy)? It seems like I can get really secure Bitcoins using a Trezor, as long as I don't mind trusting wallet service x's nodes with full account details. I really don't like the latter part, however good the former is.
I suppose a workaround is to treat Trezor accounts as dispensable in the same way that ordinary addresses are. There's no upper limit on the amount of accounts that a single xpub can generate, right?
I think your only option is to wait for Armory to support Trezor as they have promised to do. Bitcoin Core might but they move slower than Armory.
That would be nice but doubt whether we will see a potable SPV type Armory. Will keep a look out on Armory developments, thanks.

Are there any plans to include the other supported coins like LTC on the myTrezor website?
It seems like we are running out of wallets that are 'fully' compatible with with Trezor. I first made use of Encompass together with Trezor and this worked great due to Encompass supporting all the various coins. There has however not been an update to Encompass in ages and the present version is now truly outdated.
I then switched to Electrum-BTC and Electrum-LTC. Electrum-BTC no longer have support for Trezor, since version 2.3.2 and the developers suggested that one should upgrade to latest version so not sure whether version 2.3.2 should still be used. The latest version of Electrum-LTC (2.4.3.1) still works fine with Trezor so basically the only wallet that is 'fully' compatible at this stage [that I know of]. 'Fully' compatible meaning that it can handle multiple accounts or password protected accounts as well as all sub accounts.
It would be nice if myTrezor was updated to handle all the coins supported by Trezor. Will be so much better than having to jump from wallet to wallet just to access a different coin.
