I'm a bit disappointed:
1)Retina...ok, cool...it's about time it got better screen rez anyway...this was a given.
2)Qaud CPU...boring. How does this affect the vast majority of users (web surfing, email, photo viewing, some apps)? Sure, the 5% of iPad gamers may welcome it, but there will be a new iPad next year...so the CPU bump was expected, too.
3)Better camera. Again, another tech spec update.
4)Siri and dictation. As with every other dictation software package since 1981, I'll believe it when I see it. I think the world believes that dictation is still a long ways away. Even if it works somewhat well, I have no need for it.
5)Apple keeps citing all sorts of "mobile" examples as if the iPad is being used by 90% of the owners in a "mobile environment" like in the car, walking down the street, etc...on cell networks. Um, no, the majority of iPad owners are not using them in this "mobile" environment. Used at airports? Sure. Used on a train ride? Sure. But those are the exceptions. I would gather, for numerous reasons (higher price of iPad, cell network data plans/pricing, reality of cell network speeds, etc), that iPad owners are using iPads in WIFI spots and very likely at home or on vacation. Again, not using it as an iPhone/smartphone.
I think Apple's wheels are spinning a bit here on the iPad...they seem to try to push the whole "it's the best gaming platform ever!!!" mentality (when it isn't) while also pushing this as some mobile device (sure, it's mobile...but people aren't walking down the street with it surfing the net or making a call).
My bet is that the competitors see this as generic tech-specs-update while Apple left on the table much better enhancements such as: more iOS features, better iPhoto integration, something new on Facetime (3-way calling?), stereo speakers, and other stuff that I can't seem to think of right now. The tech specs are welcome...and they WILL ALWAYS arrive every release...but I think Apple missed the boat on actual features that grab your attention.
The iPad 3.0 is good...don't get me wrong...but it doesn't have the same awe-shock as the 1.0. Now let's see what the competitors release over the next 12 months and see how much ground they make up.
