But in reality, MtGox almost always has the highest price of all exchanges.
So doing bank->wire transfer->1% at some other exchange may allow me to buy my bitcoins cheaper at another exchange if the price is lower.
Plus I will not need to wait almost a week for my transfer to go through Dwolla as the price rises.
I have been a bit envious at the US users and Dwolla.
If you have to wait almost a week, that is comparable to a normal SWIFT-wire. Only thing about SWIFT and GOX is that GOX apparently demand a quite hefty fee($75?) per transaction.
Lets hope there will be some kind of decentralized network of exchanges, so that people all over the world can deposit in their local markets without all this crappy SWIFT and various conversion sites. You should be able to do a normal country-internal bank-transfer that normally takes a day or less in as many countries as possible.
If I have understood Buttercoin correctly, their aim is to facillitate something along those lines.
