Apple is trying to recreate the buzz from the ipod days and the iphone days by creating a new neet gadget that they think people want. It will sell in the first six months like hotcakes because of the apple fans out there and (honestly) because the device is flashy and nifty and lets face it people like to show off their flashy new stuff to say they are better than their neighbor.
But the long run the device will fail because it appears to be nothing more than an e-reader on a low dosage of sterroids. Personally I am tired of the days where I would have a cell, pager, and PDA on my belt. I really do not cherish the idea of luggin my work laptop around at 4.5lbs and a flashy e-reader. And that is where it is, another device that people will ultimately replace with items that are already around or will be around at a much cheaper price.
If you want technology to watch, google is the place to start. They move slower than most other tech companies but their products appear to be vastly superior. And I am not just talking about the search engine or Chrome.
Just my 2 cents. I have been wrong before.
