I'm not sold on bitcoin but this article has made me think about it again and for small in-world transactions I can see its convenience
I'm still partial to PayPal micro transactions and Google checkout for larger projects, but that's more along the lines of more traditional web-related freelance work (a model I've used for 13 years now)
But for the commercial grid, I'd feel comfortable using it for day to day purchases
