This one arrived exactly as advertised however,I thought  it would be a piece of cake, having few changes if any but there were many changes to get used to some  because of Microsoft, others because of "improvements in technology" by Dell. Being a senior, I prefer less or no change whenever possible. The set up was so complicated I had to get someone to do it.  First time for this.A walk through indicating the differences would have been appreciated...I couldn't even find the warranty card!It does work a lot faster but I still have some bugs to work out.
