I honestly couldn't imagine anyone in my family wiring USD to mtgox (from a GBP bank account), going thru the process of trading then pulling the bitcoins back to the client (which no one in my family really understands)

Now, if there was a website where you could buy bitcoins into an online account with a credit card in a few minutes, then have them (almost) instantly usable with a barcode enabled smartphone app, that would be different.
