Several years of putting up with certain banks taking several days to process PayPal transfers I would imagine. I can't see Managed Payments being any faster. Maybe credit card accounts are faster than savings, who knows. A couple of years ago Westpac used to be able to do PayPal transfers overnight when they trialled the NPP system, but they inexplicably reverted back to the old system (or at least a system that is as slow as the old system).
