So buyers need to start asking themselves what they actually want this thing that they're carrying around eight to sixteen hours a day, and often sleeping next to the remaining eight, to do.
Then they need to ask themselves what device accomplishes these tasks, and then start comparing extra features that cost more along with various price points.
After they've done all that, basically identified needs, wants, what's superfluous, then they're in a positon to actually make a choice.
We tend to be a bit conservative with our spending, using devices until they stop working, and in some cases doing a bit of home repair to keep them going when there are problems. I used an HTC Dream until the "A" key quit. We used Galaxy SII phones until her power button kept getting stuck where it was engaged, fixed that a couple times before having enough, and I used my SII until something failed and it no longer recognized SIM cards or that it had a WIFI chip. She didn't feel a need for more functionality than the SII so we replaced it with a Galaxy Core Prime, and I wanted durable without needing a case so I went with the Kyocera DuraForce XD. She spent around $200, I spent around $400, both a far cry from the $700 phones that are so common, and I expect these will give us many years of good service.
Replace the electronics when it's actually dead or doesn't meet your needs, not just because it's not as shiny as it once was.
