This is as close as we will ever get to Apple admitting their cult of personality is the primary (but not only) driver of their sales, not their products.
No, they're pretty much saying that their user experience will bring over the people who are looking at the advantages of netbooks (smaller form factor, lighter weight, more battery life, little desire to use it as a "primary computer," etc...) over to them instead. Which is something they always say.
Can you save and transfer documents to the iPad?
Probably in the same way it saves and passes notes, with a bit extra. Probably also through Mobile Me while encouraging use of online document support.
Does the iPad support Microsoft Exchange email?
The iPad runs the same OS as the iPhone right now, which supports it. Why would they take extra steps to remove such a feature?
Does the iPad support VPN and configuration management?

Can you use media services other than iTunes on the iPad?
In the same way that you can use them now; if you can transfer their media into iTunes. Also, if their media usage is built into an app that has been approved. Obviously also if it's browser-accessible and not Flash. Certainly you can enable streaming services from other sources through apps, as well. So it depends what you mean by "media services."
Can the iPad be used for videoconferencing?
There is no built-in camera, so not by itself. There is likely to be no built-in video-conferencing app from Apple to start, either. But there are already other apps that can be used as such on the App Store, and ostensibly any camera that can be connected to by WiFi, Bluetooth, or through the dock port could be used.
Will the iPad's internal storage be upgradable?
There is no expansion slot for it, and Apple has not provided it for the iPod Touch or iPhone, so... No.
Will the iPad allow multiple apps to run simultaneously?
With the current firmware version, no. But then the current firmware also has few iPad-specific features. 4.0 will likely drop or at least be detailed before the iPad launches, so anything it possible. I wouldn't expect to see any paradigm-breaking from their aim so far, but it's certainly conceivable to have some resources available for background use after switching out of an app, or having a "low profile"/widget mode that they could run in. Key factors would have to be seamless use, no additional UI clutter, no huge battery impact, and never needing to "manage" it. Certainly Apple could specify resource restrictions to keep things under control.
Will Apple allow the use of Flash on the iPad?
Doubtful. They've taken a stand against built-in code they do not control integrating with system apps for multiple reasons, and so far it has not hurt iPhone or iPod Touch sales at all. It might hurt the iPad more due to more people wanting to browse anywhere and everywhere with it--which is not as appealing on a smartphone screen--but it seems more likely that most sites will shift to HTML5 for the primary Flash use people want... video playing. And due to the messy nature of Flash on smartphones and other featurephones, it also seems more likely that Flash-required sites will at the very least build a functional HTML-access site alongside for the wider array of devices that want to access their data but can't.
