Jeanie, my heart and my prayers are with you. You are stronger than you realize, and I believe you and Tibbe make a formidable and truly loving team. I pray for better and brighter days ahead, free from the pain and frustration you are feeling.
I much prefer my iPad, but for people who like using the format of a regular laptop, a Chromebook is worth exploring. They started last year giving every incoming eighth grader to my high school a Chromebook, so I signed on to a 24 hour class this summer about using them in education which entitled me to get one also. If my students are using them, I need to be familiarized with them also. They are technically not computers, and they use Apps rather than programs. They are fairly lightweight and inexpensive, and because they have small solid state drives, they open up almost instantaneously. The one I have has a battery life of at least eight hours and is just a little more than two pounds. It's definitely worth checking out.
