I'd love to buy one, but budget tells me not to yet.

Gonna stick up with the traditional paper wallets first before I get mine. Btw, what's the difference between Case and Trezor? Aside from the price, of course.
I'd say they are probably equally secure, (different kind of security but when the cards are on the table, equally secure). However Trezor needs a laptop with USB slot and internet to operate, case is something that stands alone. You whip it out, and make your transaction, anywhere.
That sounds convincing to me, although I'm not sure as to how the GSM module was implemented on the hardware wallet. I wonder how long would that GSM support last?
