Comment Cheap Android phones are surprisingly fast (Score 1) 2
I was using $50 Android phone (512mb ram, 4gb flash, Android 6.0) for 2 years and it was surprisingly usable. When done right, it was even fast but you had to develop for it, knowing that app will run on slow phone and optimize accordingly. I even made 3d racing game that ran 50fps on it (https://youtu.be/okg61OOFUdQ). The only issue was crapware that could not be uninstalled so I was constantly low on storage. I'm still using that phone as spectrum analyzer and 2 channel signal generator.
