An event that I'm actually hyped for this year.
If the new X series can be as good M series of Apple, this would be such a huge leap for Windows/Linux laptops in battery department. Also. should help to push more devs towards AMR and maybe RISC-V in future.
I'm also very excited but I wouldn't get too hyped even if they do make great claims. The Snapdragon 8cx trailer tried hyping it up so much and that thing was really slow and didn't match their claims of days-long battery life (it was closer to 13 hours IIRC)
