Chrome OS or Ubuntu? The better cheap operating system.

I am just curious to see what other peoples opinions were on this topic. What is the better cheap operating system, Chrome OS or Ubuntu? Or in other words, at the same price of $279.99, would you buy the new Toshiba Chromebook or the ASUS Ubuntu laptop for the same price.

In my opinion, I would take the Ubuntu because you are not restricted by being a primarily online you can play Minecraft on it. ;)

Please let me know what you think.

Thank you.
