I'm at a level where my kindle broke down when I took it out during lunch (half of the screen updated, other half didn't), I just grabbed my phone, ordered a new one then and there and kept reading the book on my phone's Kindle app :D
I went from maybe a book a year to 20-24 books a year.
It's easy to keep always with you, it weighs the same even if you're reading Brandon Sanderson's latest 1600 page tome and it's always on the exact page you left it at.
And if you read longer book series that end in a cliffhanger, you can tap to buy the next one, grab more tea and continue reading even if it's 2 in the morning and you need to work the next day :D
Also: Kindle users should check out Libby[0] - it's like a public library but for eBooks, and you can probably sign up through your local public library. It's great for books that might be interesting, but aren't an immediate read.
