Certainly Amazon would be well advised to get the jump on Plastic Logic and Apple, if they can. PL has created a lot of buzz just by showing a prototype, and Apple is supposedly working on a “mediapad.” Amazon has had a lot of success with Kindle; there are even rumors a UK version will be out soon.
We'll see if the Times is right, and a new Kindle “tailored for displaying newspapers, magazines and perhaps textbooks” appears soon.
Newsflash! Gizmodo confirms May 6 for the new Kindle!
