Unfortunately, it's not Adobe DE.
We heard a rumor from from Engadget that Sony announced in their press conference new PDF support for the PRS-505.
What they actually said was:
With Sony's latest Reader, the future of digital books is here.
The Reader continues to win critical praise and for the month of December, it was the number one selling device on SonyStyle.com.
What's more, we're excited to announce enhanced support for Adobe PDFs which improves the reading experience and underscores our commitment to open formats.
When you combine a vast library of reading material with Sony technology that's geared toward ease of use and convenience, well, let's just say that's a best-selling proposition.
I followed up on it, and this is the email I got:
No specific annoucement. We're showing reflowable pdf in booth but no timeframe on availability for prs. We simply reiterated our commitment to working with adobe to improve pdf experience on prs.
Sorry for the late reply. Show is crazy. Hope this helps.
So basically it was filler for the speech. No news. Sorry.
