And suffer multiple regressions just for one progression? No thanks. I gave up a few nice things moving from Android to iOS, but I gained much more than I lost. In the end it would be quite a bit of hassle.<p>I will say that I wish Apple would either build f.lux type technology into the OS as part of the Accessibility settings, or just allow the f.lux developers to use the APIs they need. When I did have an Android phone it was a welcome tweak that made it easier to read on my phone before bed.
