This is your solution? Ok so basically unless you are linux savvy then forget securing your wallet and what about portable devices? This is not a viable solution for the majority of people. Bitcoin is a hobby right now. The only way for people to take it seriously is if the security flaws are addressed by the software itself. Otherwise how can main stream people use it for everyday purchases? Your basically saying only people that are comfortable with installing and running linux should use it. Great that's less than 5% of people who make purchases online.
How about a real solution. Right now if you ask me bitcoins should be trading for cents not dollars. Mtgox isn't secure, the wallet.dat file can't be secured in any real way see:

The cash in my physical wallet is far more secure even walking around the most dangerous neighborhood than the methods in place to use the wallet.dat file now. Forget trying to exchange currency on mtgox which also is lunacy.
