Are there any alternatives?

The closest real alternative to the Dell XPS 17 is the Razer Blade 17. These are the only two 17-inch laptops that can be configured with powerful graphics, 4K screens, and powerful 45-watt processors. The Razer Blade 17, though, is more expensive.

　　The LG Gram 17 or HP Envy 17 are both cheaper and more portable options, but they can’t be configured as high as the XPS 17.

　　Lastly, if you like the design and performance of the XPS 17, you should also consider the smaller XPS 15. It’s a bit cheaper, gets better battery life, and is easier to carry around.

　　

How long will it last?

The Dell XPS 17 should last you four or five years, assuming you take care of it. The model includes the ability to swap out components such as RAM, storage, and the Wi-Fi card. Dell also allows you to add tons of RAM or storage while configuring it — but it’ll cost you extra. The XPS 17 can be configured up to 64GB of RAM and a 2TB SSD through Dell’s own store.

　　

Should you buy it?

Yes, especially if you can make use of the extra performance and brilliant screen.
