Considering all the trouble MtGOX is having with the banks they use, now might be a good time to convert any funds you have with them into bitcoins and pull those out. Then if you need fiat dollars in the future you should deal with a broker on the currency exchange forum.
This way, all of GOX's assets will be in a form they can work with the banks and they'll be more capable of reestablishing themselves. Also, this will give the price of bitcoins a much needed boost in times of trouble and limit the amount of people who lose all their money should this situsation devolve into further action by the government against GOX.
