Didn't know this, thank you very much for explanation. I really wonder how it will performed on android powered laptops 
Well, after the latest update most of smartphones I have checked or saw on screeshots, have all same hashrate - 30H/s which give about 10 ETN coins per day. I don't really know chromebook specs, but I'm wondering too if those would get more hashpower than high end smartphones. Although they may be not compatible with Electroneum app, cause for example I can't install it on my Samsung Galaxy S2 Tablet.
