The beauty of IOS is that users are focused on tasks, rather than the operation of a computer. When I need a piece of information, or wish to accomplish a specific task, I use the proper app. Being interrupted, or having my precious screen real estate being consumed by a large advertisement not only annoys me, but actually prevents me from accomplishing my task.
For example, I have always read the Huffington Post. But their enormous ad for the horror flick Paranormal Activity endlessly ate up my screen and seriously impacted my user experience. I have since deleted the app.
As for the iPad, I do not care for folders, printing or multitaksing (which apparently eats up the battery if an app isn't closed in a particular manner.) No do I want advertisements. So I will not upgrade, and I will continue to judge applications by their overall experience, an experience now impacted by advertising.
Not wanting ads is a spurious reason, ads were put in iPhone apps since the beginning. I just buy app that didn't have ads, often there is a free version with ads and a paid version with more features and no ads, or use a competing app without ads. In the case of Huff Post, you can use their web site.
I have yet to see an iAd. And iAd isn't the only ad system used for iOS, it's just the native system.
I don't know if iOS multitasking eats battery. What "multitasking" is good for on iOS is that it does a much better job of remembering the state of the app when you left it, so you're a lot less likely to waste time to get back to a particular point in the app, and it will usually remember data that you've entered when you switch away, so the penalty for switching between different apps is a lot lower.
