I just upgraded from a Pixel 3 to a Pixel 8, and while I've read that it's a slow phone, I don't see any performance issue.

I also bought a 120€ tablet with a Helio G99 CPU and it's so much faster than my old Galaxy Tab S3 and Lenovo Tab4 8 Plus.

To me it feels like we have reached the point where these devices are fast enough like it was when laptops matured, where performance was no longer an issue and upgrades were made when the device no longer worked or Microsoft made it obsolete due to Windows 11 not being allowed to run on it.
