You're talking about poorly done software, not a hardware limitation.
Presumably, in a selector based scheme, selectors would replace
'handles', not 'pointers'. Since the PalmOS already uses the concept of
handles, well behaved apps would not really notice the change, just run
faster.

True, but whatever is done, please let me still be able to create a
pointer, assign it an explicit address space and read and write
to it. This is so much easier than dealing with drivers or some
offseted "protected mode".
