From Wired’s post about possible releases (some a lot less possible than others, these are my favourites from them).
You can’t really have an Apple rumour post without mentioning the iPhone. There are several mockups around but this is the best for me. It’s so simple, it has a clickwheel and generally looks good. This is how I imagined the iPhone prior to any images / mockups of it arose.
Secondly, reviving the Apple Newton PDA in some style.
It reminds me a bit of the Sony Mylo, only better looking.
Finally, if they were to release a touch screen video iPod, this can’t be far from what it would look like.
