I’ve used PayPal for several years now on my iDevices and PC’s, mostly for paying a few monthly subscriptions and moving money between bank and credit union. It also enables me to pay for my minor excesses out of my ‘monthly money’ rather than the family general account. I have bought a couple of big-ticket ‘toy’ items using the credit account and then paying back over a few months, or better saving up then using PP to buy the lusted after item over the net. I think PP is a useful service and I trust it more than I do big bank credit card services though that’s a little player vs. mongo player preference rather than real in-depth analysis.
Pay Pals weakness has been the network effect. In general the more members any network has the more useful it is. While PP is pretty widely spread these days it’s not getting bigger quickly enough and I have continued to use other methods of paying for most things.
PP has solved at least part of this growth problem by moving into the credit card world. Establishing a PayPal Master card in place of its own credit account. This enables users to pay through the immense existing credit card infrastructure but use the PP ‘back office.’
In one sense it’s a bit sad that PP had to just become another credit card. But they do provide a lot of other services and a way to manage and move your money around in the banking system.
