With bitcoins, I click on a bitcoin address in my web browser. That opens up a bitcoin client with the information already filled in (amount and receiving address). I then have to type my bitcoin password for the transaction to complete. Except for the authorisation step, which could be done in other ways, most of the convenience is already in bitcoins. Any other payment URI scheme could do the same thing.
