This is a high performance laptop for general application.  With SSD, the PC boot up time is very short.  It can handle most daily activity, processing document, or even some PC game.  I play a free 3D car racing game, ASPHALT, from Microsoft store without experiencing problem while playing it.  By the way, it is a great game!However, I notices around fan area, it accumulates a lot of dust.  It also got 2x 4Gb memory in it, so it makes future memory upgrade more expensive.  Its battery lifetime is short.  For example, less then 2 hours for watching Youtube with 50% brightness, or ~3.5 hours with simple web browsing and most of time do nothing with 20% brightness and also in "battery saving mode" too.  I am not quite happy with battery life time.  Its CPU is i7-6650U, 2.20GHz.  With Windows 10 Pro only, it already used up 38% memory.  Also, my laptop come with 60W Dell power supply.  It is working ok with it now.The overall condition of this laptop is ok, and ready for most PC application if the shorter battery life is acceptable to user.  By the way, it has an e-port docking capability.  I really like that feature.  It provides "no" lacking response to external monitor compare to USB docking.In term of overall performance, it should be 5 stars, but due to the shorter battery life, I give it 4 stars.
