not sure what you are talking about. the iPad had as much if not more hype than the iPhone and was broadly covered in the media. If you're talking about whether or not people want one or not, that's an unrelated issue.
I dispute that it was broadly covered in the media. Just the trade media mostly, not the general media. Ballmer's launch of those three PC slates got more general media coverage than the iPad launch has from what I've been able to see for myself. Apple dudded themselves by abandoning Macworld, more than they dudded Macworld.
Being covered in the media with question marks ie,
'yet another slate, this one from Apple, is it any different?', and crowds cheering at its launch as if it was the Second Coming are two totally different things. The iPad lacked the latter, which the iPhone had. This is directly related to whether or not people want one or not after the launch event.
What we had was months if not years of anticipation for this product just like with the iPhone, if not even more so, but as soon as the presentation was over, totally different reactions by the general public. The difference - iPad launched to a room full of media, iPhone launched to a room full of ooh'ing and aah'ing and cheering fans.
It's the difference between launching a new Harry Potter book to bookstores full of fans at midnight dressed up as Harry and Hermione, and launching it to a room full of people in the afternoon from the book business. I know which one they go with, and which one I see on my evening TV news reports the next day.
Like the Potter launches, half of the immediate media reports about the iPhone launch were about the launch itself, the crowds gasping and applauding in amazement at the product and its features. It raised the interest of the general public wanting to know what was so exciting about this new product. I don't see a single media report like that about the iPad launch.
