There is no pleasing everyone, however it's the majority sway in either the positive or negative reaction that decides the fate of any product or service. For i.e. G4 Cube, I loved it however I would not buy it, because it has too many short comings. Many felt this way and it considered a flop.
I feel the technology behind the iPad is worth noting, what I do not get is why not incorporate it into the MacBook and MacBook Pro lineup, why a separate product.
It is hard not to see that the iPad resembles the screen of the MBP, if there was a switch to go from x86 to ARM and OS X to iPhone OS X would be interesting, however Dashboard does this well enough. iPhone OS X is an extension of Dashboard.app, nothing more.
During the keynote, you can see Steve Jobs impression when he loaded a webpage with flash elements on it. Like flash or not, its part of the internet and omitting it and calling it as the best internet experience is just false advertising.

has a history of false advertising, don't believe me search it for yourself.
Though I like the potential of the iPad, it leaves less to desire. No SD slot similar to the iMac and MBP tells me this device is being crippled at the moment. Having a mic on this device leads me to believe it will support VoiceControl (limited).
Having iWork on this device seems like a last minute inclusion, in-order to separate the iPad from its competitors. See what the audience and the market reacts to and then expand on it.
I presently have an iPod Touch 32GB (3G), MBP 17" and an EeePC 10." I cannot agree with Steve Jobs sentiment regarding netbooks. A netbook might be "a cheap stripped down laptop" however I can assure you that it has no limitations on video formats, VOIP, has SD, and runs full version of all productive and creative applications, plus I can put an OS on it that I please and last but not least increase ram and hdd specs.
Anyhow Steve Jobs, keep up the good work. If you feel for one second this is the greatest achievement of your lifetime, then it has been a pretty sad day. Here is hoping.
