Installed public beta on my (important) devices. The last two platforms I held out on were tvOS and macOS. tvOS since my entire family uses it and I quietly updated our Apple TV. No one noticed.
I held off on my Mac because it is my moneymaker. I run my small business off it. I took the plunge since it is looking like we're at the Release Candidates.
My take? Liquid Glass is fine and I can't help but feel sorry for developers who spent way too much energy complaining the entire summer.
