To add to that - For sunny park reading under $150 the Kindle Paperwhite (current gen, ad-supported) is the sweet spot: 6.8-inch glare-free e‑ink, bright front light, IPX8 waterproofing, long battery, and excellent font controls. If you want something lighter and cheaper, the 2022 Kindle is portable with the same 300 ppi sharpness, a smaller screen and less powerful lighting. Tip: pair it with a simple cover and a matte screen protector to cut fingerprints and protect from another drop.
