Probably many people doing that, but the problem is that it's near impossible to get your USD out of mtgox.
So you buy BTC at $450 on bitstamp, sell at $500 on mtgox. Your USD balance goes up by $500... now what?

You can't withdraw it to repeat the cycle.
That's why mtgox prices are higher. It's good if you want to deposit BTC, speculate, then withdraw BTC... but with severely limited USD withdrawal options it's not really an exchange right now.
