A Origin of iPad: Styles in Operating Computer

When iPad was demonstrated on Jan/27/2010, people at first found it as a large form of iPhone/iPod touch.

I didn't.

At that time I was in San Diego and saw unusual things (to me) called "lap desks" in several stores around downtown. Mary, one of the host family whose room I sublet, used a lap desk for her laptop. The announced iPad and Steve Jobs using it reminded me of the lap desk and its user.
