This is a great, small profile laptop.
I imaged an SD Card with Ubuntu MATE desktop 24.04.1 lts 64 bit for my RPi 4B using rpi-imager that was pre-installed. Initially, the fit of the RPI board is tight and tricky.
Installing the screw post offsets is tricky, and you need a tiny screwdriver, which I was fortunate to already have.
The system did crash the first time through. And I saw no documentation on the Elecrow site really explaining why there were two cards. But the Elecrow OS on the card that was included came in handy to Image a new card.
I messaged technical support a couple of times and got surprisingly good results.
I am still trying to figure out the battery status options.
The keyboard layout is very well done. Many laptops have a touchpad that is in such an annoying location. This touchpad is out of the way. And they really did a great job designing this for the RPi 4. The lid closes very nicely. Throughout, the manufacturing tolerances are excellent.
