Actually, what we need is for someone like Paxum, bit-pay or even mtgox itself to make the process of conversion transparent, on demand and instantaneous.
For example, say I have 342.45 BTC in my mtgox account and I'm at Starbucks. I swipe my mtgox debit card, pay $24 USD (or whatever the bastards are charging for coffee these days) and it gets debited from my mtgox BTC account.
Replace mtgox with Paxum, who already have a MasterCard system in place, or bit-pay, who are the best at making things happen, and suddenly we can start living our lives in BTC instead of dollars, euros or pesos.
Bit-pay presented such a service at CES, you pay in BTC and they get credited in cash at their account!
I know about the service Bit-Pay showed off at CES, but what I'm suggesting is almost the exact opposite. You hold an account in BTC with Bit-pay (or Paxum, MtGox or some new company), and you can use their debit card anywhere that takes a debit card. You pay in whatever the local currency is, but the money gets debited from your BTC account at the exchange rate for the moment the transaction occurred.
In fact, it could even be the same card Bit-Pay uses, going both ways. But so far no one has come up with this particular model.
It would instantly allow people to start using BTC as the default repository of value for them. You could get paid in dollars, then instantly convert those to BTC and just use your debit card to make day to day payments.
The problem BTC has, in North America and Europe, is that people don't understand the gigantic implications of having a naturally deflationary currency. For that, Narydu, we need people like your, or me, who have felt the ravages of an inflationary currency first hand.
Give people a debit card based on Bitcoin, and it suddenly doesn't matter how much or how little inflation will hurt the US dollar, the Euro or the British Pound. The choice would be obvious.
