Keyboard is terrible, a 1050ti as an upgrade from the 1050 is stupid, 4k in a small laptop screen is the worse idea ever if you want to keep being able to see.
LOL... I like the keyboard. It works for me.
I tried 4K and promptly returned it.
I like the XPS form factor, but they've got to always throw-in in dedicated graphics card... which raises the price by $300 or more. The graphics card is a waste because most people don't game seriously on these machines or play games or use softs that utilize high-demand graphics.
The vast majority of people who buy an XPS system are using it to do stuff that they can do on a $250 Chromebook. So it is really hard to justify the extra $1750 for what you get.
The best part of an XPS 15 system - on the highest end models - is the huge, 10+ hour battery. However, I get 7+ hours out of my Chromebook. The extra 3 hours is costing me at least $1,000.
I like my Dell XPS 15, but I am being honest in that it is not worth the money that I paid for it. The form factor and the long battery life are its best attributes.
