This is the worst day in commercially available operating system security in my lifetime. There have been bad operating systems in the past (pre come-to-Jesus Microsoft, like 98 and XP...), but rarely has anyone taken a great security product (ChromeOS) and merged it with the worst currently-shipping security product (Android).
This is a horrible day for security.
Most of ChromeOS's safety "features" come at the expense of not being able to do anything; ChromeOS can't run arbitrary malicious code because it can't really run ANY arbitrary code. Yes, yes, Emscripten, the birth and death of Javascript, etc. -- the fact is that security through uselessness isn't a recipe for adoption.
ChromeOS can do most of the tasks that an everyday Internet user might want. There are lots of people who are content with its restrictions. It's far from useless.
The update system on Chrome is wonderful, in that it just happens. No strange dialog boxes, popup messages or confusing options for the computer-illiterate. It just goes ahead and does it. A power user might not like that, but it is a great system for a huge userbase.
How many insecure ChromeOS devices are there out there? Very few, I'd expect. Not many other operating systems can claim this.
Why doesn't anyone buy them then?
I have a 150$ chrome book and it fucking rocks. Does everything I need to do on the web, and I can do javascript/webgl dev on the road.. battery lasts FORever... really amazing machines.
I made a computer illiterate friend get one because I was sick of doing tech support for his windows Lappie and he loves it, and has had zero probs with it.. the only time he's called me with a problem with it was when he was trying to some fucking exe to win a free ipod. CHROME os rocks.
What application(s) do you use for development on the Chromebook?
