Seems to be the "Usable, Extendable, Efficient - pick two" scenario at its core. I remember very well a word processor on C64 (GeOS Writer I think?) that would use its own disk as swap to get around memory limits. I eventually bought a memory expansion just to get around this, which wasn't cheap in the slightest. And that's just for text! It's stunning to me how inefficient text can be when every byte counts.
