Just my 2 cents...
I for one am excited about this iPad for a couple of reasons:
First, I do most of my work on my Macbook Pro; using Ableton Live + MaxForLive to do my music, Aperture and Photoshop for my Photography/Editing and Illustrator and Sketchbook Pro for product/toy design. But sometimes when I am taking a break from work and there is nothing really good on TV, but it's on, I'll do what the average consumer does, surf the web, update my Facebook, catchup on emails, etc... but I don't feel comfortable doing all of that on my Macbook Pro while laying down on the couch (it's too hot, too heavy, etc.) and my iPhone is a bit too small for all of that (though it's still doable and great when waiting in line for a movie.) So this is where the iPad is perfect; for this general consumer type of stuff.
Secondly, for us software-based musicians, I could never justify spending
$2000 for a
JazzMutant Lemur even though most of my friends have, so I've settled for
TouchOSC on my iPhone to control Ableton Live (<-- quick test video of me using it) but again, the iPhone is just too small to really take advantage of using both hands to control all the faders, knobs and sound clips in Live with TouchOSC. So now here comes the iPad for less than half the price of the Lemur and I can use TouchOSC to do all the things the Lemur does (and much, much more!) makes this a dream come true for me and many others...
... so all I'm saying is that it's all perspective I guess. For some of you that already have a pretty powerful laptop and were hoping the iPad would do everything your laptop does for half the price, well, you are being completely unrealistic. But for those of you who loved you iPod Touches but wanted something bigger that can also create Docs/Spreadsheets/Keynotes and work with an actual keyboard, then the iPad is perfect for you! And for the average consumer that uses their computer for nothing more than watching movies, surfing the web and updating their Facebook status while checking their emails (and this is what the vast majority of the average consumer does with their computers; remember, we here on Macrumors are NOT the vast majority/average consumer; we are tech-heads) then this iPad will sell like hotcakes! And this is what Apple is betting on...
I
am surprised that there is no camera built into it. That is one of my "cons" for the iPad, other than that, I am happy and will be getting the 64GB model (now, to 3G or not to 3G,
that is the question for me.)
