People are really divided about Gnome 3 (now Gnome 4x), some love it, but many despise it.
I have used it a bit on my laptop at some point, and for some light use on the go on a laptop, it was ok. But for any serious desktop use, I would trash it in an instant, I find it unbearable.
Windows had already tried something like this with the infamous Metro start screen of Win 8, which basically looked like the Activities screen of Gnome 4x, just admittedly that Gnome looks better.
Windows 11 is trying to steer back in the same direction with their new "start menu", although you can still use desktop icons.
Gnome can become remotely usable if you install a number of extensions, unfortunately extensions tend to break at every Gnome update due to how the extension subsystem is architectured, so that bites immensely.
But for people who dig Android-like UIs, that probably works fine.
