@wastingtimewithforums: You made lots of good points. Another thing is that the number of iPads sold doesn't necessarily reflect lost sales to PC makers. Did people actually forgo the purchase of a PC or forego the replacement of an existing PC because of the purchase of an iPad? Or did they forgo dining out, going to the movies, or buying a few hardback books?
Right now, I need another PC in my house like I need hole in my head. However, I could see the utility of being able to bring something larger than a phone with me into the cr@pper. When there comes a time that I need to replace any of my PCs, they're going to be replaced by another PC. A tablet's not going to do it.
