My opinion is that bitcoin's huge flaw in regards to regular consumer usage is that two of its major benefits both work in favor of the merchant.

Can't reverse transactions: benefits the merchant, makes it harder for them to get ripped off, but easier for the consumer to be ripped off, or to force them to accept what could be an inferior product with no guarantee of a refund.

Much cheaper on fees: benefits the merchant. Consumers don't pay fees on credit cards or cash, anyway, except interest fees for CC's when you don't cover what you bought, but that's fair because you're borrowing money from the issuing bank. In fact, the consumer will see a fee where they wouldn't with other methods, as they have to pay the fee when they send the bitcoins.
