This needs to be true of notebooks too. I love my 2015 Macbook Air, but the battery lasts about five minutes and I use it way too much to take the time to get it replaced. Especially when it's old enough to not be supported soon. But if I could just spend $50 and replace the battery myself without fucking things up, which I totally would as things stand now, I would be able to use it without keeping it plugged in all the time like I used to.
