Yes, you can technically take the laptop all of those places but if you plan to use the laptop more than two hours, you need to lug a charger and have a place to plug it in. The iPad will run all day on a single charge which makes it much more portable and convenient. Plus it's instant on and easier to handle.
Yes, but the major difference is that the iPad can go with you everywhere. The couch, the bathroom, the backyard, the beach, the car, the plane, etc.
Exactly... another game changer like the iPhone... ya gotta hand it to Apple... they just keep doing it time and time again...
And we need instant on so all the losers on the airplane can call home the instant the rubber hits the road. ;-)
