For the Android app development we do for clients, I have a $10 trac phone I got from Walmart.com. That was the phone price without subsidy or any extra cost.

Android can be a bunch of hurdles, but we use same mentality as this for our app designs. I hear a lot of people in tech idolizing "good design". But is a design really good if it doesn't work everywhere? Performance should be a key factor of judging any design. Both heuristic user performance and actual measurable software speed.
