I don't make heavy use of my laptop, but I'll chime in here anyway. Currently, I have a ThinkPad Yoga S1. I got it because it's thin, light, and powerful and I needed to be able to use it in the field. The multi-mode is actually a useful feature for me; there are times I need to draw some notes on it, or prop it up for easier access/viewing. Adaptability like that is a good feature for my use case. I like it, but one big warning: keys started falling off the keyboard after a few months of light use, and required a full keyboard replacement (because Lenovo doesn't sell individual replacement keys I guess), which Lenovo forced me to do myself despite having maxed out the warranty options, including on-site service. I was annoyed but didn't fight this too much because I assumed it must be fairly simple if they allow users to do it, and I know that on my other laptop, the keyboard is the first thing you have to take out. Nope, it's opposite on the Yoga; you have to take everything, and I mean EVERYTHING, out to get to the keyboard, which is at the bottom, not the top. It turned into a massive timesink, a two-day disassembly and reassembly project because I didn't want my brand new laptop to have missing screws or little issues from being reassembled incorrectly. I hate assembling things in general and prefer to pay someone to assemble my desktops for me, let alone tiny, ultra-tight contraptions like modern ultrabooks. I still feel like I got ripped off on that, and I probably won't buy any warranty options from Lenovo in the future. Prior to that, I had a System76 17" Bonobo Pro. Basically the polar opposite of the Yoga. This was the top of the line laptop from System76 at the time. It's huge and bulky, but I did that on purpose because I wanted the functionality and the screen space. The build does feel cheap in some places, but it's held up well now for several years. Unfortunately, I had a bad experience with System76 when that laptop was just a couple of days old. The system stopped POSTing and I needed it for an on-site contracting project that was already underway (that's why I bought it). I begged them to offer an expedited repair and return process, including offering to pay extra for it and to pay for expedited shipping both ways, and they refused to do this. I got the repaired system back 3 weeks later and the system has always had little quirks and hard locks since. I have 0 interest in buying from System76 again.
