The iPad does not meet the needs of any current markets, and I don't see anything more than a niche market for the thing.
Next, you give the arguement that it's a gaming platform... the iPhone and iPod Touch are indeed becoming hit handhold casual gaming platforms. But I don't see this happening with the iPad, the device is not only highly limited in marketshare but is a bit to large for a handheld gaming device.
Lastly, the reason I don't see the iPad taking off is price.
First off, lets get something straight: None of us, and that includes you and I, can possibly know for certain whether the iPad will or will not succeedl - period! I, for one, certainly don't know? Categorically, however, stating that it will fail as many are happily doing is nothing more than an exercise in futility, therefore I won't predict if it will, or won't, succeed myself, but I'm certainly hoping it will!
Stating that it doesn't fit the current markets is a rather moot point, because we know that Apple is not aiming the iPad at the current market, but rather aiming it at what it believes will be the future market. The San Jose Mercury points out that the iPad seems like it MAY become a huge hit with the middle age crowd, including people such as myself.

Price wise, just as the original iPhone was also very expensive, lacked many features, etc., the iPad is expected to quickly follow its lead, with prices quickly dropping to around $199 for the base model. Normally, I like to wait for the second or third generations, but who knows, I just might get one of the low-enders for now. I am , after all, one of those middle-aged people that the Mercury talks about.
It's certainly true, however, that every word that you said may prove to be correct, but then again maybe not! We simply don't know yet, and simply ASSUMING that it will fail doesn't seem logical to me, but already considering the effect that the iPad is already having on the markets (just ask Amazon's Jeff Bezos for example), I'm betting that the iPad will PROBABLY, but NOT NECESSARILY, end up being a rip-roaring success. Again, however, at this point no one can say for sure.
As far as the iPad being too big for gaming, maybe, but from what I've seen of demos of games being played on it, it doesn't seem really that big to me, but what-in-hell would I know since I'm not much of a gamer myself, but I do know of a 15 year old iPod Touch user, and a rabid game player, who already eagerly looking forward to getting his young paws on one!
The iPad looks, on the surface, to be pretty much like all of the other tablets out there, none of which have thus far proven to be a success, but still, and despite what people think of all of its flaws, some are already predicting that the iPad COULD BE THE FIRST, but we'll just have to wait and see about that. As I've read somewhere, but hell if I can remember exactly where, someone stated that "the odds of betting against Jobs and company are pretty slim at best!" That doesn't mean, however, Jobs is always right, but so far, any honest person has got to admit that he's achieved a pretty dang-tooting good track record thus far!
