1. Add full phablet capacity- cellular with native call & text.
2. Make it foldable OR second screen can be magnetically joined BUT also maintaining capacity to join physical keyboard simultaneously OR develop a HUB.
3. Keep IR.
4. Add a second USB port.
5. Add HDMI port or combo USB & HDMI.
6. SD slot.
7. Audio jack.
