Preordered my Pico 4 from Amazon UK and received it in the US yesterday. To finish the setup I sideloaded the Pico Assistant onto a separate Android device and successfully entered PayPal in the app for in-headset purchases in the Pico store. My old headset is an Oculus Go, so I can't compare it to the Quest 2. To have maximum field of vision I left the spacer out of the Pico 4, which seems fine.
One advantage to the Pico 4 is the ability to play videos from the USB port, giving viewers an alternative to transferring videos onto the headset or streaming. I use a micro SD card with previously-saved videos, placed in a card reader, attached to USB-C dongle. The dongle-dangle only weighs about 20g. So far I've had no problem viewing any of the previously-saved videos I've tried. The card should be first formatted by the headset (which places the Android folders on the card), and then the videos you wish to view should be placed in the Movies folder. If you don't, the headset won't realize they are VR180 side-by-side, and you will need to set the video orientation manually each time. This is what my dongle-dangle looks like.
