It seems that for the last 4 or 5 years, Apple has introduced some kind of innovative electronics at Macworld. From various incarnations of the iPod to the revolutionary iPhone smartphone, Steve keeps raising the bar each year. So what’s in store for the Macworld keynote address tomorrow at 9 AM PST?

Some have speculated on an iPhone Nano, even going so far as to create slick mockups. I have to agree with Engadget on the possible size of such a release. Not only does a phone require more components that an mp3 player such as a radio and better battery, but it’s also unlikely that they can make it much smaller and keep the usability up on their keyboard and browser features.

While I think an iPhone Nano could be pretty sweet, I’d still prefer to see Apple release a Developer Kit for the iPhone platform.
