The Apple Expo is Europe's Apple conference -- similar to the Macworld expo in the US. Apple Expo '08 has posted details about the expo, including dates for this year's conference: Wednesday, September 17 through Saturday, September 20, in Paris, France.
Currently, there are only two iPhone events scheduled out of the over 30 planned events. It is a nice change to see that the iPhone will not "steal the show" in Europe like it does at Apple conferences in the US. You can see all of the details, exhibitors, and scheduled events on the Apple Expo website.
As we noted earlier, Apple will not be attending this year's Apple Expo.
