I live in Greece I don't know the exact amount but basically every new version of the iPhone had the same price (say 620 € for 16GB). However, inflation is measured against CPI (consumer price index) not a single product which might have specific market niche (i.e. Luxury goods). Now, a currency that doesn't slightly inflated tends to be seen as an investment by consumers rather than an exchange medium. I would very much welcome bitcoins as a payment since I believe their value will go up in the future, but how many people are willing to end bit coins instead of dollars?
