@bouncybunny you don't get it. First, you can't do all of that on an iPhone. You just can't (4.0 will help a bit though).
And what I describe is not geeky behavior while using a phone. It's what normal people do on a computer. You have your email client opened, Word, a browser with a couple of tabs and maybe Excel and you're on Skype at the same time. That's how everyone work. You don't have to be a techie. Most people use more than one program at the same time and move data from one to the other.
On an iPhone this is an extremely painful process - I know had one too. You could not copy and paste stuff from a Webpage seamlessly. You have to hit the home button which effectively shuts the app, open the second app, copy the stuff, go back to the app, find the draft email message if it was even saved, and then go on. If you're speaking to someone on Skype, you can't send them a link in the chat window because you'd have to pull out of Skype, effectively ending the voip call, find the link, fire up Skype, paste the link and then call your friend again. That limitation has happened time and time again on my old iPhone and it's not productive. That's why Jobs feels obliged to add multitasking support (although in a very limited way) in 4.0.
People who say multitasking is overrated, just don't understand how people use their devices and are probably the types who thinks Apple gets everything right and they know better. Well, they don't.
With my Palm Pre, I can do all of the stuff above without batting an eye. I don't have to shut down apps to use other ones. And webOS does it better than any other mobile OS right now, including Maemo.
The webOS interface has been celebrated and acknowledged as the best of any mobile device ever. It's the type of interface Apple should have made. It uses gestures within the screen but also has a gesture area outside the screen which enables a universal back button like gesture, a forward gesture, a quick swipe app and a lot more. In fact the interface is very Mac-like with the status drag bar that feels the same as on a Mac. And on top of that, it includes all the typical double taps, multi-touch, accelerometer and zoom features of an iPhone.
The OS does multi-threading well. But don't take my word for it. The entire tech review industry agrees it's the best mobile os currently on the market and that doing something better than that is difficult.
webOS is quite capable of being used by the general public. I'm not sure Verizon would have targeted moms and women in their campaign if it was too geeky and obscure for moms to use it. It's simpler than a Blackberry!
