When I started as a freelancer, I had several painful experiences with (a) using dualboot laptops that nearly worked but missing drivers or borked hardware was a you problem, and (b) Kickstarted Linux laptops and hardware failing. At 3am in a hackerspace, ahead of a deadline, someone pointing out wasting time on half-working drivers or failed motherboards was going to cost me my business.
Then, after sending the same laptop to the manufacturer a continent away three times, I spotted the XPS 13 Linux. Frankly, Dell's Next Day Support with the XPS 13 was what let us standardize our company on Linux for several years - if it wasn't around right then, I would've had to switch. With the Premium Support, it was actually a great option. Pick up the phone if there was a failed motherboard, and there would be a professional in the office the next day. The poor Premium Support people would get out their Linux manual and run through appropriate BIOS updates with you and did successfully fix things. One guy even fixed a second XPS since it was lying there.
Then we noticed things go wonky. More driver issues going unfixed, fewer updates, orders evaporating ("I can't explain why your order was cancelled, but I can transfer you to sales") and the range gradually dwindling. Harder to get countries with Next Day and eventually we gave up entirely trying to get a laptop and Next Day for a team member in California. We ended up going with a small independent Linux supplier, ironically. We even tried to convince a local shop to give us a Next Day commitment but nada. And then had hardware issues that took months to fix posting back and forward to the manufacturer.
We are now using Frameworks - on the basis that hardware can (theoretically) be replaced piecemeal with less drama - and, while I love the product, we had canonically the worst business customer experience I have ever seen with a failed component, over weeks, so gave up and now have a £2k laptop propping up books. It is consequently a company policy to keep a spare Framework to avoid customer impacts when something fundamental fails.
TL;DR - people will point out that many suppliers now provide Linux laptops, but the XPS 13 remains in my heart as the only Linux laptop with an (international) SLA that I could trust to build a business on. One lost billable day for a senior engineer already costs as much as a new laptop. For anyone wondering why more companies do not hand out Linux laptops, it says something when Dell is held up as the paragon of support contracts.
PS: strangely, we have never tried System76, for no better reason than there has always been something else in front of us, but if someone knows how we can get international business Next Day support, reply below.
