Then maybe you're not using me right :p
My negativity is towards attempting to push the technology backwards instead of forwards. Nearly every argument saying tablets are worthless are based on technologies that are going obsolete fast. Yes, keyboards are still necessary for many tasks, especially if you are heavy into data entry or accounting, but touch is rapidly replacing the mouse as the pointer system of choice simply because it is faster, more accurate and more intuitive. You don't have to waste time trying to find your pointer when it's the tip of your finger (or a stylus).
Yes, I do agree that the laptop serves a purpose, especially in enterprise-level tasks and IT consulting; but nowhere else is it really all that necessary as a mobility device compared to the tablet which is simpler, more convenient and more usable when you simply cannot set it down somewhere. No rule is an absolute rule; there are exceptions that are based on the circumstances at the time. Rules are intended more to be guides, then absolute canon.
