> Pick the ecosystem you like. Spend what you can afford. Buy the newest device. This is the only bit I'm not sure I would agree with today. The improvements between device generations have gotten so marginal that you don't even need to buy the newest device anymore. I switched from Android to the iOS ecosystem last year. I ended up buying an iPhone 7, and there hasn't been a single day where I thought "man, I really wish I had spent a few hundred more dollars." The 7 is fine, you know? Everything works, you get OS updates when they come out just like the newest devices do, it's not dramatically heavier or more awkward to carry. (In some ways, it's better than the new devices -- it still has the physical home button, for instance.) So, barring any huge innovations on Apple's part, I'll probably use this one until it breaks and then replace it with whichever oldest model is available then. I just can't make a case that the newest premium device is worth paying the premium price.
