Looking at the Wunder web site I came across this interesting history of Apple tablet designs, Apple: Their Tablet Computer History. We forget that the iPad is their second foray into tablet computing. The first was the Newton MessagePad, of which I had two. As much as I wanted to like the Newton, it was really too big (for a pocket) and didn’t do anything important to make lugging it around worth while. When the PalmPilot came out I switched because it could do the useful things of the Newton (calendar, address book) while fitting in a pocket.
What is interesting about the Apple tablet history is how many designs they went through of which only a few surfaced into products.
Wundr has an Epub authoring tool, Playwrite for publishing attractive works to tablets. Unlike Apple’s iBooks Author, Playwrite authors to an open standard, which is good.
