Hardware wallet
Hardware wallets are great but not the best. I want to find the most secure solutions.
Here is an example linked to from the bitkey website:

WHEN USED IN THE RIGHT WAY BITKEY CAN PROVIDE BETTER SECURITY THAN TREZOR.
Don't get me wrong, I'm not saying Trezor is worthless. Once it comes out Trezor is going to be a great addition to the Bitcoin toolbox.
However, for high value wallets, I'd much prefer a solution that unlikeTrezor:
Allows you to use it in a way that doesn't require you to trust it at all.
Built from generic widely available standardized hardware like the PC (or better yet the Rasbperry Pi).
Doesn't require you to connect it via USB to a potentially hostile computer:
Frankly, as convenient as it might be, a USB interface for a device with that kind of risk model is very unwise. Especially for people with high value wallets, which would presumably be the first in line to use Trezor. An optical channel based on QRcodes or better yet OCR of human readable text would be much more secure.
That's the idea behind BitKey. The solution we wanted didn't exist so we created it ourselves.
