I don't know if this was true at some point, but this is definitely a false statement today.

I have a Framework 16 w/o dGPU and it is perfect. It has long battery life, awesome performance, and has no thermal issues at all. Then there's all the features which I don't think I need to get into here. But I will call out support for lvfs/fwupdmgr; it's great and in line with what I have seen with Dell and Lenovo.

This is my forever laptop
