I got to play around with the touchpad a bit. While it can be a little handy to have, I find that it doesn't have the full functionality of a mouse. You can click on things but clicking and dragging is impossible. Switching up the UI is not nearly as seamless as it is with a mouse. I'll probably have to invest in a new wireless keyboard and mouse (the F1-F12 keys don't function on mine) and hook them up to the PS4. Then I can switch back and forth between them and the controller depending on what I'm doing. I have been very pleased with the beta overall and am looking forward to Phase 2. HUGE improvement over the PS3.
