Agreed, unfortunately those guys don't quite have their sht together to provide a stable supply. It is all "build to order / pre-order" vapourware.I prefer a small laptop like a Pinebook.
Normally I would consider gutting an old broken thinkpad and putting the Pi in there but there is too much proprietary weirdness going on with i.e the video connectors.
I am basically waiting for a stable laptop shell to put a Raspberry Pi in and then I think I can pretty much abandon commercial laptops (even for work) and never ever look back. It will happen in possibly about 5 years time? Can't wait.
