Yeah most cell providers subsidize phones on 24 month payoffs and then offer incentives to "upgrade" to the latest and greatest after payoff with trade in deals and the like.
Nexus 6 for over 4 years probably. Was holding on to it for a while since there didn't seem to be a good replacement that wouldn't feel like a downgrade. (still have it and it works great but I replaced the battery twice and thought it was about time to move on)
No. I have an iphone 7 that I've had for a few years now. As long as the Bluetooth and GPS work, and I'm able to use Spotify, access the Internet, and play podcasts, I don't see a need for another. I'll get another phone when this one doesn't work anymore.
Done with yearly upgrades. The 11maxpro is fine. I won't upgrade til possibly 2022 or later.
