[Paypal's] Ferguson also sounded a skeptical note. “What problem is Bitcoin trying to fix? There’s no clear answer.”
From an online vendor's standpoint, the answer is pretty clear:
Paypal is the problem that bitcoin is going to fix!
Paypal has recently suggested that they may adopt bitcoin as a funding method, this seems quite likely. Unfortunately, that won't change anything from a vendor's standpoint since Paypal would receive the advantages of bitcoin payments, while vendors would stlll be stuck with the fees and random fraud/chargebacks associated with Paypal payments.
