Google Google has just unveiled its Chrome OS operating system during a press event at the company's headquarters, and it's pretty much exactly what we expected it to be: a streamlined Linux kernel booting straight into the Chrome web browser. The code is available starting today.

They mention the 5s start as something exceptional, but really the OS is not usable after 5s you still need to connect to the network, on my home network that's often >3s and this is not even taking into account loading the webapp you want to use and suddenly the start-up time is really not that much better than a normal OS. Also Karmic brought a 5s boot time when using a SSD and that's a full OS, so the Chrome OS time is not impressive.

There is no reason at all to think that the 5 seconds doesn't include network connection setup. Kinda the whole point of putting the browser on top of a custom kernel is to make it possible to do this kind of stuff earlier in the boot process - you can eliminate the 100s of dependencies Windows for example has to manage before it can initialize the network stack. Chrome OS won't have most of these dependencies because, well..., the only thing it runs is a browser. Thats it.

Second, the 5 seconds will probably be on hardware that is 1/10th the speed of your home computer... Probably an ARM or Atom core with maybe 128-256MB of ram. In that light I think it is pretty good.

Who cares about boot times

when everyone uses sleep/resume.

But more importantly I could care less about instant boot if it means booting into a desktop that requires internet access.

ChromeOS has to be one of the most overhyped operating systems of all time. The new graphics stack turned out to be a rumor.

It's a Linux distro that locks you into the browser. Amazing!

I call BS on that and Citation needed.

Which machine starts karmic that fast from power on??

Most take longer for BIOS messages, Then those times are just to login/GDM. Gnome takes even longer to start. And then Firefox ,,,

So what they showed today (10 sec to a broswer window) is way better than Ubuntu/Mac or Windows.

EFI perhaps? That can connect to WiFi even before the kernel has loaded.

Edit--I remember Google saying in the announcement video that if the checksums don’t match up, they redownload the latest version of chrome to restore the machine. This is all before the system has loaded (because it failed checksum)—and possibly before the kernel loaded (because that’s checksummed too).. ergo, EFI firmware connecting to the wireless.

A quick google would have found you the citation

I don't think it's including BIOS time though

Well a lot of phones boot faster and are more functional than ChromeOS
