Boox Max 3, 13.3" eInk tablet. Bought just before the pandemic started and has been super useful in reader PDFs and writing notes, and even attending zoom calls(!) without any eye strain.
That looks amazing, but for 6x the time of Kindle, and roughly the same price as a good graphics card, it's a definite NO for me.
Depends on your needs. I am an academic and spend a large part of my day reading math heavy papers and taking notes as I read. A large screen eink tablet is more useful to me than a good graphics card :-)
