When will RFID hit the big time?

We've been wondering for years when RFID will finally gain widespread adoption (in our May issue we take a look at its value as an LP tool), but it has been slow going to say the least. When I asked John Koch, ADT North America's president about RFID's place in the market last year, he even said it is the $64,000 question.
Now Forbes is taking a look at it and it seems their article comes up with more questions than answers.
