I only have an android phone and a kindle. No laptop and no tv.
I am toying with the idea of getting a used iPad. I am not quite sure how I would use it. I find doing everything on the phone quite challenging. I think it would he quite nice to watch films on.
I always had windows laptops until a few years ago when my last one died and I didn't replace it on cost grounds. I have had a while to save up.
I don't have Internet at home so I use mobile data and I would possibly get one with cellular to save me tethering all the time.
I don't think this is a necessity, but I am fed up with the tiny screen. I had an android tablet previously.
