True, but this mostly applies to the USA in my opinion. I live in Ireland, EU, and over here i have yet to see a single place that accepts bitcoins as payment. Agree that in the other countries especially the US it probably will hit big much faster, but since ireland is usually 5 years or more behind implementing latest technology etc that is used in other european countries, 5 years is a very optimistic esitmate.
I mean in 2008 the best broadband you could get here was like 10mb, now the best connection you can get is 100mb, while in most other EU countries that is wayyy more
You can spend your Bitcoins at www.takeaway.com which allows you to order food/drink from many places in the EU, China & Vietnam.
