One of my TODOs in my ever-growing list of tasks has been to read more books. They can be consumed a few ways (including as food, if you're desparate enough) and each way certainly has its list of pros and cons.
The most obvious way to read a book is to purchase or borrow a physical copy of the book and read it from cover-to-cover. It's straightforward, usually cheaper if you know a good second-hand bookstore (or get lucky at thrift stores), and is how, up until the mid 2000's and the advent of super cheap consumer technology, most readers got their fix.
However, the rumblings of a new way of reading started as soon as the 70s, with mostly silence until 2007 when the original Kindle was released. The E-Reader was taking the world by a storm. Gone were the days of hoping your library had the book you've been dying to read, or having to shell out for and subsequently either store or try to re-sell a physical copy- now, with a credit card and an internet connection, you could purchase almost any book you wanted to read and carry your entire collection around on one device.
E-Readers solved the largest friction point in reading-as-a-hobby (RaaH, coming soon to a startup near you) and made it even more accessible to the masses. Even better, many libraries partner with OverDrive to allow you to borrow e-books from your local library. Undeniably, these are more convenient for anybody who wants to read more than a few books per month or have a limited amount of physical space to store books.
Even with the extreme convenience electronic book readers provide, physical books are very nice to keep around. For one, they don't have a battery and generally can last quite a while as long as they aren't outright abused. The other nicety is the tactility of a book. You physically see and feel how close you are to the end of it, rather than just a number on a screen. You have to make a real movement to go to the next page, not just tap the screen or press a button. You can huff the glue.
