After about a year using the laptop......  I still love it!  

I hate to jinx myself, but I have not had a single issue (Ubuntu 14.04).

I usually use it connected to a monitor, keyboard and mouse but on the occasion I do take it with me, I am always amazed at how small and sleek it is.  The keyboard and track pad work without any issues (though I usually bring a mouse).  I actually think the laptop is beautiful.

The only thing I would like to see is a 15 inch version.  Not really sure why 17 inch laptops have fallen out of favor...?  I think I would do more away from my main desk with a larger screen.  If I knew the m3800 or XPS 15 worked as well with Ubuntu as the Sputnik, I would consider buying one.  

Anyways,  great job guys!
