The iPad does fill a gap.

When you bought a laptop, I said, “That’s not what I want.”

(You know who “you” are. Not everyone reading this will be “you”.)

When you bought a “smart phone”, I said, “That’s not what I want.”

When the iPhone and iPod touch came out, I said, “Close”, and I bought one. I said, “I’d like a tablet-sized one.”

When the MacBook Air was rumored, I thought, “Maybe”. When it came out, I said, “That’s not what I want.”

When the iPad was announced, you said, “That’s not what I want.”

I said, “Finally!” (Perhaps)

(There’s lots of other things that could be mentioned: Newton, Palm (I wanted a tablet version), the worthless tablet PC I bought that ran Microsoft Windows, &c.)
