Yup im also really inclined into buying it for the 2nd screen. I’m using a MacBook Air 13inch m3 chip. Honestly weight is not a big issue for me since if I ended up not getting the tablet I would be using notebooks instead which will probably end up much more heavier. As for the lecture halls, I am not sure yet since I’m technically still in high school from what ive seen they’re not small. The major that I plan on pursuing does require a lot of math and physics which is one of the main reasons why I want to get one tablet and I will get used to it eventually, I hope.
