get rid of the vr stuff and add a normal touchscreen instead, make the UI a bit more phone-like, add a cellular connection, get rid of monochrome and add color cameras, make it a little thinner, integrate the battery, add a bunch of phone apps (calculator, texts, calls, browser, notes, email, camera, etc)

computing-wise, it is very similar tho, it has the exact same processor that's in my phone, just a bit more ram, can be configured to have the same amount of storage
