Why not?  If major vendors like Amazon or Google or eBay start accepting btc's today, all they have to do is immediately exchange to fiat.  In that instant volatility is irrelevant, btc is just serving as a proxy to the dollar for a nanosecond or so.  But the benefits to the company (perception of being in the vanguard) and to btc would be immense.

I have been predicting a major ecosystem announcement for about a week now, we are due anytime I think.  Lots of guys in garages burning the midnight oil on btc projects as we speak.
