Conclusion: With its built-in card reader, big hard drive, excellent screen, and RAW support, the Epson P-4000 is the best photo viewer on the market, but it won't cut it as a general-purpose portable media player.
Pros: Best display on the market. Broad video file format support. Caters well to photographers' needs. Built-in SD and CF slots.
Cons: Bulky, expensive, subpar audio quality. No WMA support. Browsing structure is entirely folder-based. Eight-character filename limit. Horrible battery life.
Excerpt: The printer was supposed to ship in January, but then February came, and then March, and each month its introduction was delayed. Finally, in early April 2004 dealers in the U.S., Canada and the UK, (and possibly elsewhere), who had placed orders five months before started to get limited quality deliveries. I was told by one dealer that they had initially received 6 units yet had dozens on back-order, and they had no idea of when more would be coming.
Excerpt: To solve this little problem Epson has come up with the P-4000. It's like a digital photo album, complete with an impressively bright and high-resolution (212ppi) 3.8-inch LCD screen, and an equally generous 80Gb built-in hard drive.
Summary: The Epson P-4000 currently represents the best compromise
between having a laptop computer or one of the other portable
storage devices on the market. You can use the Epson P-4000
both out in the field where speed, battery life and successful
data transfers are key, and later for showing your work to
clients, friends and family. The Epson P-4000 satisfies all
of these requirements in an easy to use and very stylish way.
