The new x13 Gen 6 AMD with a U-series CPU and, ideally, configured with the 70Whr battery looks very nice. Should be less than 1 kg, similar to a MacBook Air.

The new x13 Gen 6 AMD with a U-series CPU and, ideally, configured with the 70Whr battery looks very nice. Should be less than 1 kg, similar to a MacBook Air. I've used the previous generation, and it's possible to get 10 hours of use on battery with some tweaks. It's a very popular model, so it's well tested and everything should just work with the latest kernel.
