And just as you say that, on the same exact day, I start itching real bad for an Edition XS, after being a happy camper with the 400i for years. 
I guess the thing this highlights for me is that because I set my “endgame” in terms of price, not quality, after a number of years it’s likely that something newer will drop within range that will be so compelling an upgrade that I will immediately “come out of hibernation” yearning to get it, despite previously thinking I was done for life.
(To be more precise on the threshold level, I’ve latched on to the price of my most expensive smartphone as the top number I’m willing to go to for any gadget that’s not a basic necessity of life, and that’s served me well in keeping my gadgetry expenses way down so far. Of course that was in combination with being a big fan of custom Android ROMs which void your warranty, which meant there was never any point in getting phones new, at list price. Always went second-hand and much lower.)
