The new model is Intel or amd unless I missed something. They said in the video the battery life was entirely from video playback, which can be run on efficiency mode
My apologies, I don't know where I got the ARM architecture part from. I really want one of those machines, but I guess if they can't approach MacBook battery life yet I'm stuck on MacOS for now.
I think they said 22 hours of video playback in the video. If it even gets half of that for normal usage I'd be sold, the only thing stopping me giving it a shot is they are currently more expensive than the MBP and I'm not sure if they are worth it until the first reviews come in
