The reason we're not considering that at the moment is that it's totally out
of reach. The memory needed for that is SRAM or low-power DRAM, which is
either enormously expensive or immensely slow.
A far better method is to manage storage so that there's no
application-dectectable difference between persistent objects and temporary
ones, and then placing the persistent object in persistent storage.
Actually, the Newton does some of that, but it's not particularly good at
If the Tunes pages don't discuss NewtOS it's probably because of lack of
time -- it does do some things well, and should be researched. I prefer
Geos, but then everyone here knows that. :)
