Barnes & Noble Nook Glowlight 4 32GB/Black
Score: 73/100
Kobo Clara Colour
Score: 77/100Rankings

The Kobo Clara Colour is a 6-inch colour e-reader that adds a 4096-colour Kaleido 3 panel, ComfortLight PRO and IPX8 waterproofing to a lightweight design. Trade-offs include a modest 16 GB storage capacity and the absence of physical navigation buttons or a stylus. It's best for casual readers who want colour for comics or cookbooks while still valuing portability and long battery life.

The Nook GlowLight 4 provides a crisp 300 ppi 6-inch display with Ambient GlowLight and 32 GB of storage, lasting about three weeks per charge. Its small size and lack of waterproofing may deter power users. It suits Barnes & Noble fans who want a compact, button-controlled e-reader.

Professional reviewers praise the GlowLight 4 for its crisp 300 ppi display, advanced Ambient GlowLight with auto temperature adjustment, and the inclusion of physical page-turn buttons that improve ergonomics.
