GO ON EBAY and score an old Thinkpad for like $100! Anything with at least an i5 or higher processor is totally adequate for running streaming video. Even a couple yr old Chromebooks are cheap!
No one wants laptops anymore, it's either phones or pads, so the laptop market is overloaded.
I used to do major computer tech but the market has fallen out... I HATE working on phones, you don't know how anti-user-friendly they are... to pry them apart from this horrible super-glue, and then there are TINY-ass parts, like the tiny metal contacts that go in the volume and power buttons, I'm not kidding, they're the size of fleas, and if you lose them, (which you do) your phone is pretty much a brick after that.
