    It’s easy to overlook that many people don’t participate in (online) discourses. I’m sure there is a nice word for this kind of "bias": you only read the opinions of the people who have the courage and ability to express themselves. It’s possible that the "mood" you perceive by reading the posts is not mirroring a real average, since you don’t see the lurkers and their honest thoughts 😅

    Okay, the page does some lazy loading, had to scroll down and wait to "extend" the content a few times before being able to search for the word "hours". In case anyone is interested:

    We believe that battery life is the closest thing to a true Achilles' heel for the Framework laptop. In PCMark 10 Modern Office battery testing—which includes a mix of office applications, streaming video chat, and desktop idle workloads—the Framework doesn't quite hit nine hours of runtime, despite its solid 55Wh battery capacity.

    It could be worse!

    Am I seeing this correctly that the air vents are at the bottom side of the device? Does anyone know if it’s used to suck in surrounding air or to blow the heat out?

    It seems like a questionable design choice to me, especially when having the notebook on a blanket or on a lap with clothes that might cover the vents.

    It reminds me of old Apple MacBook models which had the same problem …
