SAAB,
Well, not quite the same really, because you have two companies involved (Corel and MS), and not just one (Canon).
Using your analogy, I've had a succession of DSLRs, and I knew some of my well used and favourite lenses would not work with my newest DSLR, so I kept an older camera too, so that I could still use it as a spare body. That's until I eBay them and use the cash for an even better lens! 200-400 VR here we come!
