This is going to be a good one! Finally, the world will not just look at the Mhz and go, "Oh it's only Mhz? It's not as fast as my 2Ghz."
Also, Apple does need a PDA. PocketPCs are out an work only for a... you guessed it, a PC. Only runs PC apps. Palm, Handspring, and Sony? They run Palm software and are not very reliable for a Mac (except for a Handspring, but that is another story. Apple needs a PDA that does Apple things. Pocket Acrobat. Pocket iTunes. And soforth and so on. I am already hearing whining that, "Apple already has an iPod." Why not have a product that can play mp3s and be used as a PDA. Also, for presentation purposes. Plug it into a TV or Computer and show that demonstration. Give some one a resume by plugging a network and printing it from Word (PocketPCs have it, why not Mac). Have a Falsh animation you want to improve but don't have the time? View it on you MacMate and take notes as you are on the bus.
I personally could do with a Mac product that is not a laptop but acts as a laptop. Steve, we need a PDA. Some might not want one, but most do.
