I also know many professionals who have a work computer and just want a personal device for occasional things like personal web browsing/shopping/occasionally watching videos -- things that would be inappropriate on a work computer and inelegant on a phone. These people already basically use their phone for everything -- many of them have never upgraded from their college laptop, which is now obsolete. They'd value a well-built (design, feel, screen) computer but have no performance needs.
A 2011 MBP is likely a better a general purpose PC, those early models had some great engineering. Wait for the reviews and benchmarks but the M1/M2 based MBPs are still great daily drivers.
Those old 2011 machines aren't really getting macOS security updates anymore, and compatible apps are dropping; I wouldn't recommend using anything but Linux on them. And even with a non-15-year-old battery, you'll be lucky to get half the battery life of Apple Silicon with a 2nd gen Core i5 CPU.
