Get an image tank to transfer your files over from the card, that would be even easier than getting a laptop. They really aren't that costly anymore. Here in Australia they start around $280 with a 20Gb drive in them. So if you are in the States, I would expect they wouldn't be higher than say around $200 upwards.

Look for things lIke Xdrive Pro VP300 or Xdrive 2, you will find them in Ebay as well. Don't quote me on the price in the US if that is where you are.

Only benefit with haveing a Laptop, is you can see the images on the screen and ensure they transfer properly. But there are image tanks now with little LCD screens on them as well, but cost about 2 1/2 times the price of those above.
