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.
As for future development of Equipd on Android - this is 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 how the JW Library app progresses.
