Final answer:
An e-reader is a device for reading e-books, with Amazon Kindle being a prominent example. E-readers are favored for their convenience and ease of use, although preferences for such devices may vary by age, as indicated by research studies.
Step-by-step explanation:
An e-reader is a digital device designed primarily for the purpose of reading e-books and other digital publications. An example of an e-reader is the Amazon Kindle, which allows users to purchase, download, and read books from Amazon's vast e-book library. Other popular e-readers include the Barnes & Noble Nook and the Kobo eReader. E-readers offer several benefits such as portability, adjustable font sizes, and the capacity to store thousands of books on a single device.
Studies, such as the one conducted by researchers on the usage of e-readers among different age groups, show varying preferences in technology use. A finding from such research is that there's a higher percentage of older individuals (30 years and older) using e-readers compared to the younger demographic (16- to 29-year-olds). This example highlights the evolving landscape of reading habits and the continued adaptation of digital technology in our daily lives.
