In the used phone market, a decade-old device quietly holds a promise that modern technology has abandoned: a 2016 Google Pixel, purchasable for around seventy dollars, carries with it a lifetime guarantee of unlimited cloud storage — a commitment Google made at launch and has honored ever since, even as it stripped the feature from every phone that followed. It is a small, strange monument to the gap between what technology once offered and what it now extracts monthly, a reminder that the most durable deals are sometimes the ones no one is selling anymore.
