I’m on my second Dell XPS 13 Developer laptop which comes with Ubuntu pre installed. I loved the first one but played too much Minecraft and wore out a couple of keys. I had it long enough that decent replacement keyboards were hard to find so I got a new laptop from the same line. I love the second one even more. My brother, also a Linux-using software professional, made the initial recommendation, so there is at least one other person who liked this line.
