What we like about Pocketbook Pocketbook Pro 903

  • Large 9.7-inch screen ideal for viewing complex PDFs and academic literature
  • Extensive connectivity options including Wi-Fi, Bluetooth, and 3G
  • Support for a wide variety of file formats, including PDF, EPUB, and DjVu
  • Hardware features like a user-replaceable battery, Micro SD slot, and built-in speakers
  • Advanced software capabilities for its time, such as high-quality text-to-speech and preloaded dictionaries
  • Wacom-based digitizer provides accurate stylus input without adding an extra layer over the screen

What we don't like about Pocketbook Pocketbook Pro 903

  • Unpolished firmware with several bugs and inconsistent navigation
  • Heavy and bulky device (581g), making it uncomfortable to hold for long periods
  • Sluggish overall performance and slow power-up times (~20 seconds)
  • Stylus is required for most touch interactions, which can be inconvenient
  • Screen lacks a built-in front light, requiring external lighting in dark environments
  • Limited and inconsistent note-taking features within the reading software
  • Physical hardware buttons can feel small or 'loose' for a device of its size

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.
