Pretty happy with my Lemur Pro, 3.5 years in. I just replaced the battery, which was fairly painless. Also had to replace the wireless radio, which was as easy as popping in a new one. I wasn’t happy that it failed, but apparently that’s industry wide, not just these laptops. Replacement was like $35. Other than that I’ve only had cosmetic issues, like the System76 sticker came off, which I don’t care about.
