Kindle library books can provide hours of entertainment as you self-isolate due to the coronavirus pandemic. You likely can check out ebooks from your local library, just like a regular paper book.

In the United States, you typically can check out books using an Amazon Kindle or an iOS app. In other countries, you can use alternative e-readers or apps. By borrowing books online, you can avoid leaving your house — perfect when libraries are closed during COVID-19 lockdown — and you don’t need to leave your house to return anything, either. Returns happen automatically at the end of the borrowing period.

Apple’s next AirPods go into production very soon, according to an unconfirmed report coming out of Asia. These are the wireless headphones that are typically referred to as AirPods Pro Lite, though they are unlikely to have that name when released.

But in iOS 13, you can grab the scroll bar that appears on the right side of the screen, and use it to navigate.

This is a really, really useful feature. Here’s how it works.
