Is it just me who is sceptical about anything new from Intel at the moment?
Mind you, this is not the first time that this feeling has existed, there was a standing joke amongst IT professionals in the mid 1990s that the sticker "Intel Inside" was actually a warning label, referencing the Pentium FDIV bug.
Running Steam in Big Picture mode on boot basically turns it into a more compatible/faster Steam Deck. I'd be more interested in installing Linux on it (being a Linux guy myself) if it wasn't for losing out on things like frame generation that you get from the Windows graphics drivers.
