Yeah. GP's point is just plain wrong, if he was concerned about 3rd party stuff lasting for more than one phone purchase, iPhones are clearly the winner with only have two connector options since 2008 while keeping their form factor consistent for two generations (and there are adapters for the first switch, and possibly a third switch this fall, where adapters are still plausible all the way back to original accessories).

Samsung and most other Android manufacturers aren't even guaranteed to maintain physical dimension compatibility between different models of the same exact phone (S6 vs S6 Edge, for example), let alone if you were to just stay with Android as an OS and were switching between manufacturers each upgrade. No way in hell you're keeping any nice-fitting docks or cases around for more than one Android phone purchase.
