I have a Kindle fire (which I call my tablet) as well as a Kindle paperwhite, which is solely for books. I got the tablet from Jen, and use it as a backup to read the forums and FB etc, but I hate typing on it (I much prefer a proper keyboard) so I really only use it to read the forums and play games.
My Kindle is often in my bag so if I'm sat having a coffee somewhere on my own I can take it out and read
I watch for books on offer, like 99p or free (I don't get Prime or Kindle Unlimited) and I have a few waiting to be read at a time. It's great for sitting in the garden or on the beach to read in the sunshine, or nowadays I read in bed with the light out and it doesn't disturb Tom
