If you upgrade your phone every year then this roadmap is pointless, but for most people this is a pretty interesting insight. Of course it’s speculation, but this guy is quite accurate.
If you have a 2 year cycle, upgrading this year seems like a real goer. A three year cycle means I would like to upgrade next year.
Sure, next year we’ll get a better battery, the 6x zoom, and USBC, but the year after will be a major change from the pill to the hole. I don’t see the pill notch as a big change in that regard. Especially the smaller 13 P/PM notch.
Sure, he could be wrong, but we’re about 4 iterations away from having the full screen. If you time it right, that’s only 1 upgrade between now and then. Again, if you upgrade every year, it doesn’t matter and you can enjoy everything Apple releases and not worry about what’s coming next year.
