As usual - as it has been with all previous Apple gadgets - speculations have been running wild and each day sees new revelations and details from unnamed sources. Apple - also as usual - keeps a straight face and says nothing.

Official announcements may come in January, February or March - depending on the latest report you read. Real and documented information is rare and speculations and predictions are running wild. Truth be told - no one seems to have a clue and Apple might as well take us all by surprise (just remember the iPhone).

Most speculate on a bigger, touch screen - similar to that of the iPhone - probably central to the design. Rumours have it that Apple is currently also negotiating print media content for its iTunes store - something that would certainly benefit from a slightly bigger touch screen, according to BusinessWeek.com
