Apple is good about only announcing real products you can buy. They don't do tech demos. It's always, "here's a problem. the new apple watch solves it. here're five other things the watch does. $399."
I agree that Apple does a better job, but wasn't Apple Vision Pro announced 240 days before you could get it? I think it's a pretty safe bet that Gemini 1.5 (or something better) will be available anyone who wants to use it in the next 240 days.
Apple aggressively keeps products under wraps before launch fires employees and vendors for leaking any sort of news to the press .
Also an hardware product that is miles ahead of competition in terms of components and also needs complex setup workflow (for head and eyes) something apple has not done before being 7-8 months after announcing is not really comparable with a SaaS API in terms of delays
