Just my 2 cents on the Android wallet.

If we want a closed-source wallet it will mean building it from scratch.
- increases the amount of effort required
- introduces higher probability of bugs
- increases the development, testing and refinement time
- will be orders of magnitude more expensive

I see why people want closed source on this, but it makes the project exponentially harder, longer and more costly.

Is there not a huge PR advantage to being known as the first community to create a PoS wallet?

It's a tough decision...
