All in all though, this means I will be much less likely to support any Kickstarters.
With Amazon Payments, I did not have to re-enter my CC#. Backing a project became an impulse buy. Click, type PW, done.
Now I have to go get my wallet, type in a bunch of information, which gives me a LOT longer to think about if I really want to back a project or not.
Indeed the primary reason I use Kickstarter over other funding websites is because I don't have to re-enter that payment information so often.
