Trezor does not store a single address, so no single address can be imported. Trezor stores master seed for deterministic wallet hierarchy.
I don't think anyone is asking for private key import. What they want is have the BTC swept from the entered private key on to the next available address in the deterministic sequence of the Trezor. Once the sweep is complete then the imported private key is thown away.

I don't think anyone is asking for private key import. What they want is have the BTC swept from the entered private key on to the next available address in the deterministic sequence of the Trezor. Once the sweep is complete then the imported private key is thown away.Hmm, I did not think about it this way. This is of course doable, but it would require new interface, because it does not fit any current Trezor interface + input of such private key is not implemented. Personally, I prefer not having another interface which will be used by one of the thousand users once. (security) expert who has a paper wallet should have thought through how he is going to spend coins from his paper. Non-experts will never use this. Implementing this thus gives nothing to the masses. There are more important milestones to achieve than polluting Trezor interface with stuff almost nobody would use.
But what is the advantage of entering the key into trezor instead of directly into the web interface. Once the whole key is entered the address is sweapt within seconds (I assume) so even if an attacker was infiltrating the PC, no harm could be done.
Well, considering highly specialized malware for stealing sweeping private keys to Trezor; such malware can disconnect Trezor just at time when it detects private key entered to UI. Then there's enough time (few seconds are actually enough) to send such private key to remote server and let it sweep all balance. Not very likely, yet possible.
However me and stick had some brainstorming about sweeping private keys and although it's not very comfortable, we came with a solution which might satisfy paranoid users. It won't be worth a hassle for small amounts, rather for people sweeping their lifetime savings to Trezor.
Am I wrong?
Yes, you are wrong. The moment you give your private key away, the malware might be faster than your intended software doing the sweep. Example: malware monitors all text inputs for Bitcoin addresses and when it sees one it immediately uses it. Your software waits until you press Enter. :-)
So people finally realized that paper wallets are fine until one wants to actually spend them?
That is a valid point. I might start using honey pots for importing now too :p

Well, not really
It is just very complicate/much work to do. Using a cold PC to prepare a transaction and then broadcast it would be 100% safe (if no errors were made) but still, not very convenient.

Perhaps direct entry of paper wallets into the Trezor is the most secure method of inputting rather than trying to get a secure channel outside of it.
To enter pure hexa, i.e. 1-9A-F, you need just four keypresses, but for backspace and enter you would need more. The problem is that this does not work for Trezor. Trezor does not store a single address, so no single address can be imported. Trezor stores master seed for deterministic wallet hierarchy. The good news is that this is much better/secure than a single address. The bad news is that your paper wallet cannot be input.
It would be possible to provide entropy using the two buttons. If you did it in binary, it would be just 256clicks. The problem is that human is not good at providing random binary sequences. I think that guessing 256 human provided clicks is really hard, but trust me: The entropy provided by the computer is a better quality. Unless you use dice/coin for each bit. But if you do use coin, the process would take long and no sane person would do it.

I think I may have even come up with a way to do it with just the 2-buttons and keep number of key presses down to a minimum. I thought of it while thinking about old computer games when I was a kid. Not as simple as typing on a computer but still simple like programming a tv remote perhaps?
Turn them into codes and provide a nice clear cheat sheet:
The Trezor button are L/left and R/right
(I put 4-length codes but I'm sure it's higher, hopefully you can figure out a scheme that keeps the length short)
Backspace:
L L L L
1 = R R L L
2 = R R R L
....
A = L R L L
..
Z = R L R R
ENTER/EXIT:
R R R R
Then when at the private key entry screen on the Trezor and you can see your progress as you punch in the codes. When they are done they will just start pressing R. The screen could also provide visual clues as to what x/4 they are on.
It still requires time but at least once someone entered a few they would probably go pretty quick. Better than cycling through every digit.

First batch of TREZORs from eshop orders are on their way to happy owners! ;-)
Mine was shipped too. Where there any first editions in that orders?
nope
It was a long shot anyway.
I am actually very pleased with the speed of the order processing! Good job guys.

No
. We still have few First edition replacement pieces for RMA purposes and we'll eventually offer them for sale, too. But not yet. First batch of TREZORs from eshop orders are on their way to happy owners! ;-)

Would anyone consider selling me a first edition metal trezor still in the package? If so pm me.
I know someone who still has it mint, I guess. I don't have contact details, but will ask him to contact you on the next bitcoin meetup. he always is present there
Thanks!

Just got the tracking number as well! Thank you.
Woohoo... got my tracking number! Looking forward to this. Thanks for all your hard work on this guys!
