I don't want cameras strapped to my head, I want a lightweight display I can wear unobtrusively and doesn't make anyone near me nervous (doubly so since this is from a company known for invading privacy), even if it's a fairly low resolution one. Version 1 could even be 4 lines of text and I'd still pay for it - I already wear glasses every waking moment of my life anyway.
Pair it with my phone, give me driving directions which don't require me to take eyes off the road. Remind me of things when I arrive home or get in the car. Let me read texts. Overlay that 9-minute pasta timer in a corner of my field of view until it runs out. Blink in a corner to remind me that my lawn sprinklers are still running, so I don't go to sleep forgetting to turn them off (ahem).
I'll probably learn to use a swype-style keyboard while keeping the phone in the pocket and looking ahead through the glasses.
Come on, I grew up awed at the HUDs of Robocop and Terminator, give me a damn HUD, it's 2023.
