I bought this laptop for my son as a back-to-school item. We used it for around 3 hours reviewing the hardware, software, operating system and setting it up to be ready to use. My son lives a 4-hour flight away in Mexico. Once there he used it for an hour then the hard drive went out. It will cost $80.00 in shipping cost for me to get the laptop ship back to the U.S. then to Amazon get it replace or repaired then send it back to my son in Mexico. The cost to get the hard drive replace on the Dell Latitude E7270 UltraBook Screen Business Laptop in Mexico $80.00.  I will be writing and adding more to this review.
