I like to upgrade them (the battery life, screen, refresh rate, etc. have all gotten consistently better over the years), I usually have one to leave at work and one for home use, and I give the hand-me-downs to friends and family.
You can also sell them back to Amazon for a pretty good bonus when it’s time to upgrade. I think I sent back an old paperwhite and got $50 + 20% off my Scribe.
Right now I have an Oasis and a Scribe that I use about equally.
Reading is one of my bigger hobbies, I read around 100 books a year on Kindle.
Interesting, thank you. With regard to the refresh rate, I saw a recent eReader recently, the difference with my nine year old eReader is striking indeed.
And you can create a second, small partition/filesystem if you still need to persist some things. I used to have very little data to persist and I would mount/write/unmount every time I write to deal with possible power issues.
My tinnitus (from a single loud party), which I had before noise canceling headphones, gets worse with noise canceling headphones, but only temporarily, like 2 or 3 days.
I found out as well that my headphones plays my own voice back to me so that I dont shout, but was able to turn that off in the settings (Jabra 2), which seems to help.
No, exactly not. The cost of infra is dominated by the transmission network and that transmission network is very expensive to build and maintain, a superconducting network would have some massive advantages. Besides, the losses are in the 5 to 7% range for a typical grid which may sound great in theory but is still a function of the distance between the generators and the consumers. So you can't really put those where you want them, you put them where you have to in order to minimize the transmission losses or you'll have to live with larger losses. Superconductors for the grid would give far more freedom in siting and would allow all kinds of neat tricks such as transporting solar power across the planet based on the day/night and seasonal cycle and likewise for wind power depending on where it is currently blowing the most.
Generating costs are a small fraction of the final price of electricity, taxes and transportation are the big ones.
If you just look at superconductors as a replacement for any old piece of wire you're going to miss out on a whole bunch of advantages, it is a clear qualitative difference which enables solutions that are entirely undoable today. Yes, there is HVDC, but the lines are expensive and due to the high voltages involved are not easy to interface to or from. They do have some unique advantages, being DC they allow non-synchronized grids to be connected.
