You can actually use Photoshop to edit in a non-destructive manner by using layers skillfully. However, it tend to make the .PSD files very large and performance begins to bog down when you go past a certain point.
indeed you can, and you could even redo the whole chain back through LR (or Aperture) by making a new rendering in LR, then using that to replace the base layer in PS; but such a process would be painstaking in comparison to a fully integrated workflow; i suppose it might be worth it sometimes; and i was once used to saving many versions of (what were then considered) large Photoshop files as work progressed, it wasn't that hard ...
Scott Kelby had some interesting things to say about non-destructive editing in an interview, I think on The Candid Frame podcast (not sure). He feels as I do that the value has been a bit over-hyped ... just like the dictum for obsessive keywording, etc. Both have their value, but not every photograph needs to be able to be re-edited from scratch forever, and not every photograph needs forty keywords applied.
that's worth ponderation, though i think part of why i don't break out of Aperture much is just to avoid the cognitive overhead of maintaining multiple workflows
