Usually the answer is that they can't be without it at all.
So I never recommend Apple laptops for business owners unless they have a spare... a spare "anything" will possibly suffice especially if everything they do is online.
I only tend to buy Dell business laptops: great build quality and a 3-year next business day onsite warranty are worth every penny imo: Not as flashy and fancy as the XPS stuff but they have/had quality issues (as the commenter below mentioned).
Also, I could not imagine our business having spare computers.We have 600 employees maybe now, and we need more and more computers as more users need to perform work on a computer these days.
How many of your about 600 PCs die every year? The spares you need are much less than that number, as you can buy (or recover from repair hell) new computers over the course of a few days to recover your reserves.
I tend to upgrade every five years: my current laptop (MacBook Pro) is from 2016 and I see no reason to upgrade anytime soon. My 2011 laptop (MacBook Air) is still running fine. I could even work on it still, but it would not be a pleasant experience.
Not sure if there's a precision model for the xps13.
This isn't any kind of attack on them, it's just that when I was searching for a laptop they seemed to be having some issues and even the warranty replacements had issues. Which really sucks because the XPS lineup do look enticing for me.
I could find ways to do most things. Nowadays it's a lot easier.
Musicians make music, so they have to rely on other people making tools for them, whereas toolmakers can just make better tools for themselves.
That is, if you can avoid reinventing the wheel, which we aren't great at.
