While not really applicable to any of the situations he described; I really wish more applications/companies/etc would use 2-factor authentication. It really baffles me that more applications DON'T use it, such as banking applications where I personally consider 2-factor auth a must.
Bank "security" = forced < 8 digit alphanumeric code that can be overridden on the phone if someone knows my birthday. I know because I hacked into my own bank account anonymously and was able to transfer funds. Best I can do is refresh my password regularly and hope nobody finds out my birthday :P (there's more to it than that, but that's the gist of it)
I also have found that carrying around cash is a lot more secure than using my debit card. My debit card has been copied, and money stolen from my account, 5 times. To date I have never had my wallet physically taken from me nor lost any money that way. Cash is compatible with every system I interface with in-person and it carries no service charge. This seems backwards to me. Banks really need to get with the program.
So long as there's an option available that doesn't require a smart phone (or worse, a specific OS), I agree completely. As a quick example, Blizzard has had an inexpensive device [1] in addition to phone apps.
