• The Paperwhite 2 has a resolution of 1024 x 758 pixels with 212 ppi, while both the Paperwhite 3 and 4 offer a higher resolution of 1448 x 1072 pixels with 300 ppi, providing crisper and sharper text.

2. Front Lighting:

• All models have front lighting, but the Paperwhite 4 includes 5 LEDs compared to 4 LEDs on the Paperwhite 2 and 3, resulting in more even illumination.

3. Waterproofing:

• Only the Paperwhite 4 is waterproof, with an IPX8 rating, which means it can withstand submersion in water, making it more suitable for reading by the pool or in the bathtub.

4. Storage Capacity:

• The Paperwhite 2 has 2 GB of storage, the Paperwhite 3 has 4 GB, and the Paperwhite 4 offers much larger options with either 8 GB or 32 GB, allowing for more books and content storage.

5. Audible Support:

• The Paperwhite 4 is the only model with Audible support, enabling users to listen to audiobooks through Bluetooth headphones or speakers, a feature missing in the Paperwhite 2 and 3.

6. Weight and Color Options:

• The Paperwhite 4 is lighter than its predecessors, weighing 182 g (Wi-Fi model), and comes in multiple colors like Twilight Blue, Plum, and Sage, in addition to the classic Black. The Paperwhite 2 and 3 are only available in Black and are slightly heavier.

These improvements in the Paperwhite 3 and 4 over the Paperwhite 2 focus on enhancing screen clarity, storage, usability near water, and support for audiobooks.
