While I agree that security is not
currently a huge risk, that doesn't mean it isn't relevant. As said above, this becomes a much bigger deal when adoption grows, especially less-savvy folks. You get both: less-knowledgeable users, and more-determined attackers. To suggest otherwise is like saying "Well I never use my airbag. I guess I don't really need it."
There is also an aspect of
perceived security. One of the reason I made
Armory Offline Wallets, was so that people had the tools to secure large amounts of Bitcoin without all the uncertainty and complexity of hacking the Satoshi client to do it. People holding thousand of dollars in Bitcoins can do so with confidence that they don't have to
worry about theft, which may have been a barrier for some users pondering a large investment... and hopefully business owners will feel comfortable adopting Bitcoin -- they already have enough risks associated with integrating Bitcoin into their business model, hopefully the huge boost in security can remove one dimension of uncertainty.
The fact that lots of people have identified they lost money through online services (loss & theft, sometime indistinguishable), is what I hoped to solve with Armory. Give people the tools to manage their own Bitcoins, without relying on someone else -- which appears to be a non-negligible percentage of voters reporting loss.
