You make a fair point; I don't make my observation from any internal knowledge, but from a perception of how the win-phone stood as an option during the time period you cite, namely that it didn't fit the needs I described. The lumia 640 was still larger, missing a removable battery, and very tied to the MS ecosystem; in that time period some of the early droids had these functionalities + the sliding keyboard + smaller form factor at a comparable price point. Now, that last point re: non-MS ecosystem may shoot my thesis in the foot from a pragmatic standpoint, but again, I'm talking "pipe dream getting foot into market" here. I would emphasize my point re: less viable competition for the niche I'm describing though, since as you say "perhaps now is different"; I'm certainly having a much harder time finding my next phone upgrade that fits my criteria now than I felt like I had in 2009~ and in 2012~.
