Something that also should be mentioned here, the larger the card the
more "heap" or "RAM" is used to keep track of every byte on the card.
So the larger the card, the more heap is taken if you use the space or
not.  Therefore newtons with less heap (ram) such as 1.x should stick
with smaller cards such as 4 or 8mb.  Personally I would go with 4 and
carry a few cards, as it is better than frequently running out of heap.

While you can freeze unused packages to save heap (every installed
package takes heap if you use it or not), it does slow down usability
since you have to thaw it before use.  Sure it only takes a second or
two, but if you have to do a it a lot, it gets annoying.  Still it is a
way of carrying more packages around (especially if not used much) than
you normally would without running into the heap "the system is unable
to do what you asked, restarting may fix this problem" wall.

You can use NewtCase to solve both of these problems, but it can get kind of messy, and it's too slow for frequent use.
