The hassle is the relentless debugging and glitchiness after slapping Linux on a Windows computer. System integration is a thing, and it's hopeless for a random user with zero access to firmware and chip/board documentation.
I bought a high end serval a couple years ago. I think they stopped producing that line. We never got any firmware updates to address battery life, wifi, sound, bluetooth, trackpad issues. I think they perhaps realized the fu'd, and that product line might have represented a sunk cost for them. I can't blame them if thats the case from a buisness pov, but as a consumer, I'll shop elsewhere for my next 'it just works' linux laptop. Many more options now than a handful of years ago.
Also, the support and open firmware.
