Packages can be installed onto pcmcia storage cards. In the case of the emate, however, this is not a huge luxury, because you've only one pcmcia slot. Thus use of, say, a wireless card and that software pkg at the same time is impossible.

More memory can, however, be added by way of an internal memory card which goes in the battery compartment, and which also widens the data bus. It makes a big difference to how the machine behaves, but the cards are hard to find.
