Dwolla is great, ... but for smaller amounts their $0.25 per-transaction fee is a limiting factor. Especially if what you want to buy is only $0.99, for instance. Also, when you receive Dwolla as payment and want to spend that money using your bank ATM/debit card, after you withdraw funds it then takes a couple days for those funds to reach your bank (via ACH). For now, Dwolla is available for U.S. accounts only as well. Bitcoin has no such limitations -- it is just software and a network protocol.
