Android is really getting bloated these days, my nexus7 becomes nearly unusable these days(the launcher is not responding, etc), haven't used chromeOS. I recently bought a netbook(ACER) for $190 that I loaded with Linux and does everything I need, really why do I need ChromeOS? Both ChromeOS and Android are OSes, it's like two Linux distributions, I don't know why they should "merge", what's the benefit for doing that? is it merge-able considering Android is such a JVM-hack?
