I had ordered this laptop with an extra Samsung 500 GB drive in hand, knowing I would replace the conventional drive immediately.  I'm delighted each time I use it.  It absolutely ranks as my secondary computer so my demands aren't as much as I do all of my Revit (3D) work on my big computer, but as a casual use this compute is terrific.  I still have a few issues to work out.  I assumed that I would need to buy a new battery and that reality is a little closer than I anticipated.  There are some driver issues that I am trying to resolve, but otherwise.. It is the best purchase I've made in a long time.
