And, what's your point? Why this isn't an automatic update - I thought that the premise of ChromeOS is escape from Windows' update nightmare.

Because it has not been supported by Google for 2.5 years.

And, again, what's your point? Why this isn't an automatic update - why does Google not put the effort of upgrading their old systems while Microsoft just do it? Apart from the ill-fated Surface RT, Microsoft's old devices still receive periodic updates with minimal intervention. Why Google can't do the same thing?

Edit: actually, Microsoft is even kind enough to support clusterf***s that are not even their fault - https://arstechnica.com/gadgets/2017/07/clover-trail-systems.... As another comment pointed out, just give security updates if it's too onerous to upgrade to the next OS - which in CN60 is demonstrated to be a pure business decision.

Because it went out of support. 5 years is their term for Chromebooks/Chromeboxes. I paid $220 for it. Was it infuriating that they did not support it longer? Yes. But $220/5 = $44/year. I gave info to people who were curious if this worked. It did.
