Indeed, MtGox is trading about 5% higher than other USD exchanges right now.
There is a (small?) risk that this could be a sign of bigger trouble to come. I don't know if I'd be comfortable leaving USD funds in MtGox right now. Maybe that's a risk others are willing to take.
Agreed. It may be smarter at this point to buy Bitcoins with you USD balance and sell them for EUR, GBP or JPY. The volumes are smaller but it is possible.
