I'd be very interested how well dell notebooks last - do they have similar 'design flaws' as the current gen Apple notebooks (keyboard, display cable)?
It's just one data point, but I have an XPS 13 model 9350 that's now 3 years old (used daily) and I haven't had any faults develop yet.
Another data point, I have an XPS13 L322X that's a couple months shy of 6 years old that's also been a daily driver. I've replaced the battery, but it has otherwise stood up surprisingly well. I was amazed when I looked up how old it is.
I'll pass it onto the kids once I get one of these shiny new ones and will be replacing the keyboard and fan when I do. Some of the plastic covering on a few of the keys is starting to come off and the fan bearings are starting to go so sometimes it's louder than it ought to be.
I have an XPS15 that's almost two years old at this point. It doesn't have the same flaws as an MBP but overall I feel like it may be slightly less durable.
The screen isn't covered with Gorilla Glass and gets marked up the way Macbooks used to. The monitor hinge has a little slack in it and the power connector is a bit loose.
The trackpad has been surprisingly good. The keyboard is decent. I also like the fact that I was able to swap in 32GB of memory and an NVME SSD of the make and model of my choice.
Mine came with a Fujitsu SSD, I think. I swapped in a much larger Samsung 960 Pro. I've ordered several of these for others and they all came with a Samsung OEM unit of equivalent performance.
In summary, the hardware doesn't suck and it runs Linux, which is the best part.
