It honestly wouldn't have occurred to me that this is feasible - my mental model of a "Raspberry Pi" is basically what the first-gen models were. But apparently it's been a while now, and their newest models use an ARM Cortex-A76 CPU, which is actually pretty respectable - only a bit behind my 2014 desktop, from the numbers I can find. Absolutely capable of running a web browser on modern Linux.
The Raspberry Pi 500 series with the CPU built into the keyboard are very capable little computers and extremely easy to setup, maintain, and re-image. I could literally mail them a new microSD card to plug in if they needed a new system but it's never been a problem. They use the default Raspbian image or whatever it's called these days, Raspberry Pi OS. It's perfectly suited for their needs and is rock solid.
