There should be a trezor public wishlist, so that we can make suggestions, and the public can give feedback on what they would really like to see in future updates.  Ultimately it could only help sales for the guys at Trezor...

But I know you guys are not iOS/Android developers. Hiring someone is of course an option and I would not mind, because that would not harm other goals. But even if iOS was top on the wishlist, you should not do it, but focus on what you are good at...

I think as a general rule of thumb, you should keep your trezor away from moisture.   Even if it was advertised as waterproof, I wouldn't go throwing it in the pool.   I would assume the metal model is more resistant than the plastic one, just because of the materials it is made of...

As is answered twice per page no, and it probably never will be.

I wish they would put them up for sale for a higher price.   I would pay 2x the regular price for a metal one, just because I like the way it looks.

Buy plastic one and pay somebody to do the case for you. slush mentioned it's mostly manual work anyway and plastic is almost for free...

it seems to achieve the same thing, but i see a few shortcomings:
1) no screen to verify transactions. If the PC fed it incorrect payment info it would sign it - whereas a trezor requires you to confirm the address and amount shown on its screen and click the OK button
2) I dont see any PIN protection for payments
3) I dont see any password capabilities, or the capability to run multiple totally seperate wallets on it like the trezor can (using a different pw for each)

There are 2 ways of confirming the transaction. Some keyboard scheme I don't really understand(and apparently is complicated), and also a multisig account with GreenAddress.it. GA.it will send a text asking for 2FA with information about the transaction. So both your computer and the text would have to be send maliciously. 

Obviously not impossible, but a much higher bar than a vanilla computer.
