Its a nice laptop and portable than other models. I bought 15Z with i3 processor and happy with performance and windows 8 makes it smart . Due to it ultra slim it makes machine portable. Back-lite keyboard helps to work at any time. Screen manages its brightness according to outside light. WiFi also works fine for me. Dell provide incredible support for your each but also small query.
But battery backup is poor with low video quality.Though Dell providing LED screen it does not produce expected quality. Sometimes Touch-pad settings does not work and you need to open touch-pad settings.Web cam quality is not up to mark.
Thanks
