I disagree. If I spend 15 minutes using this service, and if I believe the service offers something others don't (I don't know if this is the case---I haven't tried it), then I've just achieved something I couldn't do otherwise in that 15 minutes. If it saved me even 5 minutes of my time compared to another service/software, I'd value that at $1-5 depending if I was at work or using it during my free time that I could have spent on something else fun. Now, getting me to pull out a card or log into PayPal is an uncomfortable, high-mental capacity activity, which I might not want to do during my free time. That's the real problem behind internet micropayments.
