Yes, everyone wants to accept bitcoin, but that's not news. The real question is why me as a user would want to pay with bitcoin? When I pay with credit card, I get 2% cash back. When I pay with bitcoin I have to pay Coinbase 1% fee and I get zero cash back. In addition, I need to make sure the price of bitcoin hasn't moved between the time I bought them on Coinbase till I make the purchase. It's just a complete no-brainer that I should use my credit card whenever I can, instead of bitcoin.
And just to clarify, the businesses are not really accepting bitcoins, they are only accepting them temporarily so they can immediately convert 100% into dollars.
Not throwing your private key at everyone and having to deal with credit card fraud paper work every 6 months? that seems like a pretty good reason but maybe it's just me...
Well, with bitcoin you won't have to fill any paperwork, since once they are stolen, they are stolen forever and you can't do much about it. At least with credit cards you can have limits and most credit cards have pretty sophisticated fraud-detection systems that limit the damage.
