Plus pressurized pens are useful in more than just zero-g. I used to use one along with a waterproof note pad for note taking in the field. They're also not prohibitively expensive, although the ones from Fisher itself carry a pretty huge brand name markup, other companies sell them for a couple bucks each.

Wait....waterproof notepad?! How does a notepad hold the moisture from the pen? Or is this like a grease marker situation?

the paper doesnt necessarily need to absorb the ink, the ink just needs to dry on the surface is such a way that it adheres well enough it doesn't rub off, or stay wet.

So really, you want a high adhesion, quick drying ink, which would basically let you write on any surface it'll stick to.
