Summary: This is one of the best laptops I have ever seen however as soon as I turned it on a high pitched whine came from the machine. Dell quickly replaced the motherboard which made no differences and have told me there is a widestread issue with these machines and have offered me a full refund. I would rather they fixed the issue but seems like they don't have solutioon. Pity as it is such a great machine.
Summary: For what you're spending, this is a very nice system. The specs are some of the best available and the IGZO IPS QHD+ screen the screen is absolutely beautiful, expecially when you find images or videos that use every single pixel. You'll find most programs will scale properly; however, you will find some programs are not programmed to be used on an 1800p screen. This will be resolved in due time.
Summary: DO NOT PURCHASE UNLESS THEY HAVE FIXED ALL WIRELESS ISSUES. THIS HAS BEEN GOING ON FOR OVER A YEAR NOW WITH THEIR XPS LINE AND IT SEEMS LIKE THEY CANNOT GET IT RIGHT. YOU ARE ABOUT TO SPEND A LOT OF MONEY OF A LAPTOP WHERE THE WIRELESS WILL CUT OUT EVERY 15MINS.
