I'm undecided. I really like the idea, but for some reason it looks like BB has decided to require a Paypal account in order to pay by credit card (or I have misunderstood something). I simply refuse to create an anccount anywhere (and especially at Paypal) for doing such a simple thing as paying with my credit card. This also means that BB will loose me as a supporter in the near future.
Looking at this page (especially the quote) from Paypal,
(https://www.paypal.com/cgi-bin/webscr?cmd=p/mer/WAX_landin...), suggests that I'm far from alone in refusing to create an account for credit card payments.
