    Good purchase and cost/benefit

    I have one month with this laptop and I'm really glad to work in. I use every day Virtual Machines to do development besides the office work in the SO host and really flows using Vmware and Win 10 like host.

    I add 8 gigs more to have the laptop on 16 GB and the experience is really good. I don't gaming so fot the use that I did like programmer and power user is a excellent user experience.

    The battery runs using the virtual machine, having internet access and music, from 4 to 5 hours that's for me is not bad. Using like tablet is a good experience too. I travel a lot and that is why I decide to purchase one pc like this. I made other test using like tablet in one fligth of 5 hours using netflix and email and still remains with battery.

    I repeat that I don't use this laptop for gaming and I won't. It's only for bussines purposes and development. Don't have ethernet plug and I have to purchase one for USB 3.0 port but I understand this because the body is slim and have a really good wireless. I would like to have the screen more close to the laptop bezel but it's ok.

    In conclusion, for the use described it's a great purchase with a balance of cost/benefit. I hope this review helps somebody.
