caveden, it's small enough (physically) to fit on a keyring I guess. So such a person would just carry it with them.

hmm...
a great device.

Even better would be the standalone;

same thing with a display that can show QRcodes, a camera and a micro usb port switchable to charge only (no data) mode.

Question folks - which Android app can do offline transactions using QRcodes and a camera?

I guess you could do it with mycelium (successor of bitcoinspinner)

EDIT: wait, what exactly do you mean?

Trezor uses two-factor authentication - something you have (trezor) and something you know (PIN). If an attacker has physical access to your Trezor and he also controls your computer, you're screwed.

Not wanting to be negative or anything - Trezor is definitely a great improvement on security since our greatest worry right now are malwares - but we should note that its currently configuration makes it vulnerable to the "evil (and tech-savvy) maid attack".
Somebody tech-savvy enough with physical access to your place (a maid, a boyfriend/girlfriend, a roommate etc) could deliberately infect your computer while you're not around to get the PIN. Even a hardware key-logger would suffice. Once with the PIN, s/he only needs to steal the device.

I don't think that's a major risk, in the sense that it won't happen frequently, but it's worth noting anyway. Some people can't afford to fully trust those they share their living space with. Think college students for ex., particularly computer science college students who happen to share their room with people who were just put there by the residency administration. They barely know each other...

I'm confused as to why the PIN code is entered into the wallet application, rather than the device itself

This is covered in our FAQ: http://www.bitcointrezor.com/faq/#safe-enter-pin-computer-not-trezor

surely that increases the risk of a successful physical theft. Assuming the PIN code is not changed on a regular basis, using the device on an infected workstation would essentially render the PIN code useless if attacked through a combination of both digital and physical means.

Trezor uses two-factor authentication - something you have (trezor) and something you know (PIN). If an attacker has physical access to your Trezor and he also controls your computer, you're screwed. But with physical access to the device, having physical keyboard doesn't improve the situation too much.

There's a vote for (commercial) bitcoin project of the quarter Q3 2012.

Trezor is one of the nominees.

Afaik the nexus 4 has the usb-otg supported removed from the kernel as the hardware for whatever reason can't supply the 500mA required by the usb specs. Iirc that's what some commit comment in the source said.

I don't think any specific ROM is needed to communicate with a generic HID device (I'll recheck though)

May Bitcoin be touched by his Noodly Appendage
I can't find the time to install a CM... Maybe one day. Hopefully before Trezor is available.

Ramen, brother.

I just looked at the links, you need a deodexed ROM
Not sure the people aimed by Trezor know what is a deodexed ROM, how to install it, and want to do it...

I don't even know what a deodexed ROM is. Using cyanogenmod it was as easy as installing a zip using recovery (ziddey-otg-M3-06281551.zip) I used guide found here: http://forum.xda-developers.com/showthread.php?t=2181820

EDIT: oh, and: noodly appendage-shake!

(which modern Android phones do support)
Nexus 4:
 - modern Android phone
 - no OTG support


of course it has OTG support. Just verified this last week by connecting hid devices.

of course you need to root and install some stuff.

You only need a kernel patch to automatically mount disks, otherwise you can just use an app.

IT works, you just need a second battery.
