I've got a laptop with a 500 GB HD and 4 GB of ram. Why does Matlab say I've got 8 Terabytes of contiguous memory?

That's the theoretical limit that MATLAB can access on your 64-bit system, which is independent of how much RAM and Swap you have. The actual limit is the "Swap Space" shown above - 4642 MB free.
In case you're not aware of these, there are a few tech notes on memory and MATLAB that you might find useful. This one is a good start.
