Just a comment meant in no way to criticize the OP. His/Her expectations are understandable but unrealistic. The massive growth in the iPad customer base seems to be coming from two very different audiences: (1) those who own (or want) smartphones, including the iPhone and expect a device that improves on the user experience with the apps available in that environment; and (2) those who believe the iPad is a laptop (or even a desktop) computer replacement.
In fact, it is neither. But those who expect a super smartphone are more likely to be completely satisfied than those who want to substitute an iPad for a computer. Unless, that is, those in the latter category adjust their expectations.
I know because I came from the latter group. And even worse, I was used to a PC environment and all that that entails. I have found that the iPad is an adequate substitute for my travel-centric netbook once I added a bluetooth keyboard. On the other hand, the iPad can't replace my desktop replacement category laptop even when I travel, much less my quad-core multi-monitor desktop system. It wasn't designed to do so.
And for the record, it doesn't mean I can do without my Android smartphone, either. Apart from the obvious fact that I can't use the iPad for most telephone calls, I can't put it in my pocket, either. And when I'm in the car, I'd rather have the turn-by-turn navigation my phone provides.
The iPad does what it does very well. I'm delighted with it. It fills about 80-90% of my (casual) internet browsing needs. Its great battery life (compared to my laptop and even my netbook) means it's significantly more portable. The display is wonderful in comparison to my phone, but I'd rather watch movies on my laptop, desktop monitor, or my TV. My wife's Kindle is better for reading books, but the iPad is nearly as useful. And then there is functionality that only the iPad provides. Note taking that combines typed text with handwritten diagrams. Sketching applications that pass the time even for a non-artist like me. And interactive books and games I can play with my daughter on the living room couch.
The bottom line is that the iPad covers a market space that neither computers nor smartphones cover as well. But that doesn't mean it's a universal device that replaces either completely. At least for the present, consumers should understand the limitations as well as the strengths of devices like the iPad.
