Just have Chromium OS installed on one of my machines, thanks to this guide. I use Sun Virtual Box as the virtual machines with Chromium OS image from gdgt.
If you already use Chrome browser, you will be very much familiar with this OS. It looks exactly the same, except the existence of 3 small icons at the top right corner of the OS (on my 4th screen shot), representing the battery indicator, Wifi and other menu similar to what Chrome has.
But seriously, is this what Chromium OS all about? Chrome browser with all apps on the cloud and… boot in 7 seconds? Not too excite with the boot time as my systems up almost the time. You may said that it still in beta, but beta should give an insight what the final product would be, am I right?
It may works at certain developed countries only where internet connection is everywhere, but not on developing countries where internet is still an expensive ‘commodity’ and with limited coverage. I have not much to say as there is very few things to mentioned with regard to Chromium OS.

Bookmark sync for Chrome browser is all you need to synchronize your bookmark across multiple computers. It is so cool that I have installed it on every machines that I own.
It makes your life easier, switching from one computer to another without hassle of exporting and importing bookmarks to multiple computers.
Install Chrome browser beta version 4.0.223.16 to enjoy this features.

Follow these steps to start sync.
To sync your bookmarks, follow these steps on each computer that you’ll be using to access your bookmarks:
- Open Google Chrome.
- Click the wrench menu
.
- Select Synchronize my bookmarks.
- Sign in to your Google Account in the dialog that appears.
- If you’ve already enabled the sync feature on another computer, you’ll see a prompt asking you to confirm that your different sets of bookmarks should be merged together. Click Merge and sync to finish the syncing process.
- Click OK.
You can enable sync on as many computers as you’d like.
Once everything in place, you’re ready to go.

You can stop and resume the bookmarks sync anytime you want. But I prefer to have ‘Sync now‘ features, so that the bookmark will appear immediately on Chrome browser on other computers.
