My recommendation - if you are looking to purchase a device, and you really want to use Equipd, then stop thinking and get an iPad or iPad mini - you won't regret it.
Update 30 July 2014:
The future development of Equipd on Android is still up for consideration, but the priority has been lowered by the advent of the official JW Library App which runs on the Android platform.
At this stage I am going to wait and see the direction the brothers take this official app and what features it will support. If it doubles-up with the primary features of Equipd then I will probably not port Equipd to Android. So let's wait and see a bit longer how the JW Library app progresses.
