I pre-ordered a PICO 4 128GB Headset for £379 from Amazon.
The few points that swayed me were:
You can wirelessly play your PC VR games from 'Steam VR'. They also give you a USB-C cable if your wifi is not fast enough to handle 5G
It's got built in feature to adjust the lens (make then wider / narrower)
Built in support for people who wear glasses (they give you a headset spacer)
And most importantly, you don't need a fucking facebook account. 🙂
