WRI claim that a general (multi-level) undo is impractical in notebooks 
because of the complexity of the environment and potential size of the 
files, but I would claim they could do a LOT better than the current scheme.

For example, the could restrict the UNDO mechanism to cells that are not 
generated (i.e. not output), and possibly the undo stack would only go 
back as far as the previous evaluation.

I would have thought a multi-level undo is pretty vital in an 
interactive program!
