What we like about Sony Prs 350

  • Extremely compact and lightweight design, making it genuinely pocketable
  • High-contrast E Ink Pearl display provides sharp text and a clear reading experience even in direct sunlight
  • Highly responsive infrared touch-screen interface that does not impair screen clarity
  • Solid build quality with an elegant aluminum-clad body
  • Excellent handling of various file formats, including ePub and PDF with text reflow capabilities
  • Intuitive user interface with helpful features like a built-in dictionary and note-taking with an included stylus

What we don't like about Sony Prs 350

  • Complete lack of wireless connectivity (no Wi-Fi or 3G), requiring a USB cable for all book transfers
  • Higher launch price compared to competitors like the Amazon Kindle, which offered more features for less
  • Small 5-inch screen may require more frequent page turns and can be difficult for those who need very large text
  • No integrated light, making it impossible to read in the dark without an external lamp
  • Lack of audio support, meaning it cannot play audiobooks or music
  • The Sony Reader Store was considered less extensive and more cumbersome to use than Amazon's ecosystem

Verdict

The Sony Reader Pocket Edition PRS-350 is an ultra-compact e-reader featuring a 5-inch E Ink Pearl touchscreen with an 800x600 resolution and 16-level grayscale. It offers 2GB of internal storage, capable of holding approximately 1,200 eBooks, and supports formats including EPUB, PDF, and MS Word. Its main pros include an exceptionally lightweight 155g aluminum design that is truly pocketable, a highly responsive infrared-based touch interface that avoids screen glare, and a battery life lasting up to two weeks (roughly 10,000 page turns). However, its notable cons are a lack of Wi-Fi or 3G connectivity, requiring manual USB transfers, and the absence of an SD card slot or audio support for audiobooks.
