Out of the box the machine was slow and after a week needed resets - "powerwashes" one to four times daily.  Attempted numerous fixes but after a few weeks gave up and am now returning it.  The touch screen is very sensitive and I would close out chrome by accident numerous times.  The default settings keep taking over, dimming the screen to illegible levels and startups are slow, which is not what a chromebook should do.  I like chromebooks in general, and enjoyed using one for over a year prior to buying this one.  The Chromebook Go was suppose to be a step up from the cheap one I had before.  Unfortunately, despite being twice as expensive, it was no where as good as the cheap one.  Just ordered another brand today.
