IF:
1) There's no tracking, spying, monitoring or profiling of my movements, actions or data the device records by any company or government agency;
2) I have the option to direct remote storage and output to a server under my control, not just a nebulous "cloud" owned by Amazon or Google or whoever;
3) I have complete control over who gets to access what data from this device;
4) I don't have to sign away my rights, privacy or allow any third party unrestricted use of the intellectual property in any images/audio/video or other data the device creates;
5) I am not bombarded with advertising and marketing as part of the experience.
I am willing to pay more for the device in exchange for these points, because I don't expect to get something for nothing and I'm not willing to trade my privacy or personal control for "free" or "cheaper" hardware and services.
If Meta can meet and respect these expectations, I for one would definitely go for this over Google's offering. They have the potential to capture a huge market here, from all the people who are more concerned about the Google than the Glass, without considering the people who want the extra immersion and functionality Glass does not provide.
