They haven’t been produced for like a decade. I had one for traveling also. But now, or pre Covid I should say, I usually traveled with an iPad Pro with a keyboard or a MacBook Air. My current MacBook Air, which is the newest model is very fast, has a 13 inch screen, and 18 hour battery and weighs 2.7 pounds. There are probably lighter, comparable Windows machines or Chromebooks. I know my Chromebook is. No room for netbooks unless they really rethought the concept.
