Now that the Macworld 2009 is just a couple of weeks away all kinds of Apple product related rumors are floating around again. One of my favorite is the iPhone nano rumor, as I really would like to have a smaller iPhone that fits nicely in my jeans front pocket.
The iPhone nano rumor started even before Apple introduced the first iPhone. Now according to MacRumors case manufacturer XSKN added an iPhone nano category to their website. XSKN has a reputation of releasing information about new cases before Apple actually announces new products. The company sold iPhone 3G cases before the announcement by Apple and also showed cases of the unreleased latest iPod nano. That an iPhone nano is coming eventually is almost certain. There is a market for small phones, especially if Apple manages to get a very high-res small screen into the iPhone nano it could be a real killer.
Apple has lowered expectations though for big new announcements at the Macworld 2009 with Steve Jobs not showing up and Apple's pull back from future Macworld expos.
I bet Apple is not choosing Macworld for the iPhone nano announcement. They will make a special event for that and Macworld will be all about Snow Leopard and OpenCL.
