Looks like a promising service; but, like other similar services that rival PayPal (ie. Egold, Stormpay, Moneybookers), it won't affect PayPal much for a while. PayPal is still the preferred method of most Ebay buyers and PayPal still has the most accounts/users. People likely aren't going to go through the hassel of switching from PayPal to another service unless there is a significant advantage associated with the new service (which there isn't, yet...)
