Sounds more like World Wide Hardware Conference. How will they announce so many products and talk about software too? I hope they release the hardware in the weeks to follow.
The keynote is 1.5 hours. They don't have to take more than 20-25 minutes to refresh the whole mac line if they don't want to. The last few keynotes were padded with multiple (pretty boring) 5 minute software demo's/walkthrough's that were unnecessary. Keep in mind, the conference lasts 5 days!! We're just talking about the keynote, which is exciting, but only 1.5 hours out of 5 whole days!
