    Verdict

    The PocketBook Touch Lux 4 Limited Edition is a premium e-reader featuring a 6-inch E Ink Carta™ HD capacitive touchscreen with 1024 x 758 resolution (212 DPI) and an integrated frontlight. It is powered by a 1 GHz processor and 512 MB of RAM, with 8 GB of internal storage expandable by up to 32 GB via microSD. This edition is distinguished by its unique gold finish and includes a protective cover and an extended warranty (typically up to three years). Main pros include its exceptionally light 155g weight, support for 19 file formats without conversion, and physical page-turn buttons. Notable cons include the lack of a color temperature adjustment system (smartlight), a non-flush screen design, and relatively slow performance when handling complex PDF files.
