What would you with multi-tasking that you can’t do now?
I don’t view it as a multi-tasking issue. It’s more of a multi-waiting, or multi-notification issue. Even with 10 apps on your Mac or PC, switching from one to the other requires some kind of effort. Mouse click. Keyboard. Something.
To go from one app to another on the iPad (as with the iPhone and iPod touch) requires a similar effort. A touch, a swipe, something.
The difference has to do with why you go from one app to another (Mac or PC or iPad). Notifications. When I get an email message, I get notified (because email is running in the background, which is what multi-tasking means in this case), and checks and downloads messages. Ditto for Twitter or Facebook or other apps that somehow need to communicate beyond the device. Add to that calendar notifications or other alerts.
Some of that capability exists on the iPhone, which negates the issue of multi-tasking, per se. Obviously, the reason for a formal lack of multi-tasking is to prevent half a dozen background apps running at the same time and sucking all the juice from the battery. It doesn’t look as though a lack of multi-tasking has hurt sales of the iPhone or iPod touch.
How would you hold the device if it had a camera?
Apple is very shrewd when it comes to stacking on features. Initially, with new products, they stack what is needed (not what pundits think is needed) for a good customer experience. Then, they add the right features at the right time to keep the price tag high, to get new customers on board, and create a migration path for everyone. Look at the iPhone. The first version didn’t have 3G, no MMS, no video. They sold like free steak. The next version added 3G and a few other goodies. They sold like free steak with AAPL stock. The 3GS came with even more. Same price.
As to a video camera on the iPad, you can bank on it for the next gen, next year. It gives us something new to buy. Imagine how clogged AT&T’s sluggish network would be with a few million iPads using iChat for videoconferencing all day.
I suspect the camera will sit up top, so you talk into the device, not much different than iSight on a Mac.
