I actually got a Lemur Pro for work, and I really love it. I had an XPS 13 2020 Dev Edition for about 2 months, and long story short, Dell support sucks, and we decided to return the device, and went with a Lemur Pro as the replacement.
Pros:
- Great battery life, I develop in typescript currently and am getting a full day of battery
- Using a dock, I can get up to 3 displays, maybe four if I try with the on-board HDMI port
- Charges with USB-C with up to 65W, so one cable for everything.
- Full sized USB A ports for quick flash drive access
- Typing on the keyboard is very solid (however I do have one con listed below)
- Can turn off camera via software (with Pop_OS)
- Linux from the get-go
- Came packaged pretty well
- Lots of goodies came along. Pins, stickers, etc. Not everyone will care but I thought it was a nice touch
- Recyclable box, plastics, tc came in the packaging.
- It's SUPER light
- Good amount of customization in my opinion
- Has another m.2 slot you can put your own or buy it configured and filled up
Cons:
- Regardless of configured RAM, first slot is always 8gb, so anything beyond 16gb total will always be non-dual-channel. Believe this is soldered.
- Touchpad could be bigger
- I believe the max brightness is something around 300 or 350 nits, which may cause issues when working outside, haven't had the opportunity to because of COVID
- The keyboard has pg_up and pg_down on top of left and right keys, which is rather obnoxious and I wish they would have went with pg_up and pg_down for fn + arrow instead.
- Possible con for people: SD card slot is only micro, not full sized
- Only one USB-C port
- No thunderbolt
- Power button is unintuitive imo, but I'm nitpicking at this point
- Compared to the dell, the bezels are a bit larger than I like, but again, nitpicking/doesn't really bother me
I haven't tried the Lemur but I have a Darter I bought this year. Surprisingly powerful and feather weight (which was the major reason I bought a laptop this year). It runs Pop OS which, surprised me again, is very convenient and a nice usability improvement on top of Ubuntu. Highly recommend.
I don't have any experience with their hardware, but both of my personal computers run Pop!_OS. If you're looking for a distro in the Debian vein, and aren't hardcore Free software (I think they include drivers to play with proprietary hardware), it doesn't get much better. I don't see myself switching away from 20.04 in the next few years, at least.
