I guess it depends on what you call portable. If you want it to be portable like a cell phone then no. If you want to go out in the back yard and surf and read, or read on the train, the plane or car then it is portable. If you carry a purse, briefcase or backpack it is portable. Everyone seems to get caught up in what it isn't. It is not a 27" iMac or a business laptop, it is not a cell phone. It is an iPad; which may be the next Xerox, Fed Ex or Zip Lock.
