Actually, both matter. These charts almost always show 1 side or the other, but it does matter both ways. On the Apple side, there's no decisions to make, and upgrade paths are very clear. On the Android side, there's plenty of options and it's a very competitive market. If you don't like the current offerings, 3 months will see a bunch of new devices.
