What is sheerness?  Anywho, this thing is tiny.  Wifi built in is a plus, crazy fast for networking and general usage.  So small, I have to find more crap for my desk.  External cd-rom could be a negative but it's not really.  I bought an external and it is fine.  The rack to hold this thing up is a total ripoff.  I would have 3d printed one if I had know how tiny it was.  I would buy these again in a heartbeat.
