Looking for an ARM SoM for a palmtop

I have been attempting to design a palmtop/HPC sort of device, and
 so far I have established some basic guidelines for a modern
 implementation for such a device.

There are my (personal) goals.
1. The device must be be around 20cmx13cmx1cm when folded.

2. It must have a battery life of at least 5 hours when running on
 a 4000mAh battery.

3. It must be capable of running a full desktop environment, eg:
 GNOME, XFCE, Plasma, etc.

4. All the drivers must be open source, or the datasheets required
 to make them must be freely available

5. Bluetooth and 2.4GHz Wi-Fi must be present.

6. 4 USB slots, 3.5mm headphone and mic jacks and a full size SD
 slot must be present.

7. The display, cameras, etc must use MIPI connectors.
