E-Reader Buying Guide: Everything You Need to Know

E-readers allow you to carry thousands of books in a single, transportable device.
If you’re interested in buying a new e-reader, there are styles, specs, and feature sets you should know about.

Screen Type:
Choose between E Ink (paper-like, easy on the eyes, long battery life) or LCD (color display, touch-capable, more like tablets). Some devices combine both (e.g., newer Kindle and NOOK models). E Ink screens vary in resolution and contrast.

Size and Weight:
Smaller devices like the Kindle or NOOK Glowlight Plus are lightweight and portable. Larger ones (like Kindle Fire HD 10 or iPad) offer big screens but are less portable.

Interface:
Controls may be button-based (more accurate, less intuitive) or touchscreen
(easier to use, but uses more battery and can smudge).

Battery Life:
Basic e-readers last longer. Devices with Wi-Fi, touchscreens, or web browsing drain faster.

Features:
Some e-readers are for reading only, while others (like NOOK or iPad) include music, web browsing, and apps.

Formats:
Check file format support (EPUB, PDF, TXT, etc.). Open formats like EPUB are more flexible; proprietary ones like Kindle’s AZW are more limited but can be converted.

Capacity:
More storage means more books/media. Some devices support SD cards for extra space.

Store Access:
Devices like Kindle, NOOK, and Kobo have direct store access. Others require
manual downloads.

Price:
Many good e-readers are now around $99. Tablets cost more but offer extra functionality.
