I ordered a copy of Ayreon's new CD, 01011001, recently and paid for it (via Paypal) in Euros, not really giving it a second thought. Today I updated transaction records in my accounts, and registered the amount in US dollars payPal sourced to meet the exchange rate.
This was the point at which I realized, in a tangible sense, that the US dollar has lost half of its value against the Euro since the last time I bought a CD from Europe. It wasn't all that long ago.
