    Verdict

    The PocketBook Pro 903 is a legacy 9.7-inch e-reader featuring an E Ink Vizplex display with a 1200 x 825 resolution and 16 levels of greyscale. It is powered by a 533 MHz CPU and 256 MB of RAM, offering 2 GB of internal storage expandable up to 64 GB via a microSD slot. Its standout characteristics include comprehensive connectivity with Wi-Fi, Bluetooth, and 3G, alongside a passive Wacom digitizer that requires a stylus for touch interaction. Key advantages include built-in stereo speakers, a 3.5mm headphone jack, and text-to-speech support for multiple languages, making it a capable device for both reading and audio content. However, users may find the device significantly heavy at 581 grams, and its performance can be sluggish compared to modern standards, with a lack of an integrated front light for reading in the dark.
