PDA Functionality on AX 2012 R3

I would like to know more details on the standard functionality on AX 2012 R3 on the PDA functionality, in terms of what it contains as features and what are the limitations. I do understand that To-Increase has an add on the PDA functionality, but I would like to go with the standard functionality....I would like to mainly do the following but also look at additional features (if any)

1. Stock counting using PDA

2. Stock transfer in and out using PDA

3. Purchase order receipts using PDA

4. Issue to Manufacturing  using PDA

5. Prepare materials for Shipment using PDA

The solution should be able to connect AX database directly and update directly.

Thanks
