I picked up a radxa zero last year and have been quite enjoying it. the hardware is better than a pi zero but costs less. same with a lot of other SBCs
but raspberry pi has a lot of inertia behind it, a lot of software and hardware support. people will keep using them, just like they keep using Ubuntu, even though it's a soulless corporate husk of what it one was
i used to look at cached pages all the time. it was particularly useful if the current version of the page was different to Google's cached version, or if the page was down. then the button to open the cached page disappeared without explanation. one of the many ways that Google search now is worse than it was 20 years ago
