The Brax example you posted was a YouTube link, which is an instant skip for me. Personally, no phone with dated tech is going to interest me. Their WallUp looks interesting but there’s no product just a waitlist and an animation. I already have TRMNL displays around my home, so I’m in their market.
For Lenovo, their Yoga was interesting ~15 years ago but Aeroblade is just a proof of concept, and thinner laptops in general are irrelevant to me. I use a powerful laptop and a tablet, not a compromise between them.
