Thus, it should come as no surprise that the other end of the market is also receiving active encroachment by low-end smartphones. Now, ARM is suggesting that it's actually quite conceivable for OEMs to produce a 'smartphone' for as little as $20 — as long as you compromise a bit on those things which actually make it a smartphone in the first place. So, is this just more graying of the line between smartphones and feature phones? Or is this an indication that the feature phone (as we used to know it) is finally well-and-truly dead?"
