chromeOS provides a LOT. its very easy to use and quite reliable, and its super easy computer illiterate people to get into.

I have tried most distros, pretty much every single one that claims to be user friendly. not a single one holds a candle to chrome/chromiumOS.

for a lot of people chromeOS is genuinely a good experience that Linux simply cannot replicate. the polish is very much beyond what other distros provide.
