You don't have to subscribe to Amazon Prime to use the other TV services. You can also install Kodi if you want to play back local media.
The FireStick will use USB power - so you can use your TV's USB ports rather than a separate plug. It also has an Ethernet adapter - I think only the more expensive Apple devices use Ethernet.
I replaced all my USB-C and Micro-USB connectors with magnetic ones. No more orientation worries, no more fumbling in the dark, no more not-inserting-it-hard-enough. Just bring the two into proximity and them magically snap together.
I have separate resolutions for my laptop and external monitor. I found that adjusting the font scaling was the easiest way to get a consistent size across both.
I'm using Wayland, which has helped me loads with display issues. Have you tried switching to that?
Set your meal preference. I usually choose "Asian Vegetarian". That guarantees you a (somewhat) tasty curry and you'll also be served first.
If you're travelling to somewhere with a significant timezone change, prepare beforehand. Start shifting your body clock about 1 hour per day. Most importantly, shift when you eat your meals - that seems to be the key for me.
Unless you are flying business class or higher, there's no real way to get a good sleep on a plane. All the gadgets in the world won't help. Get a thick sleep mask and some earplugs and hope for the best.
Once the seatbelt sign is off, take your shoes off. You'll feel a lot more comfortable. Put them on if you go to the toilet though!
I think they're useful for building algorithms. But the tools themselves aren't powerful enough for anything too complicated. I hope that changes though!
To be clear - they also work with data transfer (well, except the power bank and neck cooler).
I copy ebooks to my reader over USB, transfer photos off my camera, and print photos - all via USB-C.
