Can you elaborate a little on this fundamental design flaw?  As a naive 
and unfortunately focused elsewhere personality, I don't immediately 
know of a better model for creating a spreadsheet.  Is it "just" a 
problem of sparsity?  Or is there a much more sophisticated method for 
memory sharing of various similar cell attributes, perhaps analogous to CSS?

Thanks,
