No I don't think lenovo lied (though that's, you know, historically not at all out of the question), it's just extremely common practice for there to be hardware differences between two design revisions of a system which manufacturers don't feel the need to announce. I think it's also quite easy to verify that this was/wasn't done beyond a reasonable doubt, and the Dave2D video presents no evidence that they took this very basic step. It's an oversight that a more established group would be given the benefit of the doubt on, but since this is a fairly obscure channel it instead indicates a lack of rigor that, compounded with the other minor oversights in the process, makes trusting the validity of their conclusions very difficult for me.

I don't doubt that Windows 11 will perform worse than SteamOS, it's an absolute trashfire of an operating system, but as cathartic as it is to finally be able to rub this in the face of m$ stans, we should wait until we're certain we're right instead of leaping to a premature premature celebration that backfires embarrassingly on us (ala apple fans).
