Agreed. I'm paranoid and go one step further and don't do banking or log into any other critical account on a wireless device (smartphone, tablet, laptop, ...).
Scary stuff. On my Android I do nothing that has to do with money, and nothing requiring a password (except FreeRepublic - and I use that password for nothing else).
At home we have just one computer for financial stuff — banking, shopping, etc. We do our business quickly, then log off ASAP. Do zero email on that, as so much bad things sneak in via email.
Technology is the worst thing ever, and the best thing ever, depending on the use.
If you still write checks, the person in the line behind you is going to want to smack some sense into you. At the end of the day, if you're reckless with your devices you're more at risk than others.
Unfortunately the biggest thief in our lives is the U.S. government -
