how about we add a few bits and let people do wallet locks?  i think most of us at this time are hoarders who know bitcoisn will be worth 100,000$ per bitcoin one day

a wallet lock is something that only honest users would be interested in imho.. u can use a password to lock/unlock but not to send coins

the fact is.. yeah windows has exploits that pretty much allow hackers at anytime to own your system, they are in the wild before they're even patched and no windows  box is ever totally secure at any given time.. a 0-day hacker can always rape yer bitcoinZ
