Well, the multitasking argument just went down in flames. Apple's
iPhone OS 4 is going to introduce multitasking on the iPad this fall,

No, it's a very limited form of multitasking.
From the iPhone SDK info on developer.apple.com:
• Background audio - Allows your app to play audio continuously. So
customers can listen to your app while they surf the web, play games,
and more.
• Voice over IP - Your VoIP apps can now be even better. Users can
now receive VoIP calls and have conversations while using another app.
Your users can even receive calls when their phones are locked in
their pocket.
• Background location - Navigation apps can now continue to guide
users who are listening to their iPods, or using other apps. iPhone OS
4 also provides a new and battery efficient way to monitor location
when users move between cell towers. This is a great way for your
social networking apps to keep track of users and their friends'
locations.
• Push notifications - Receive alerts from your remote servers even
when your app isn't running.
• Local notifications - Your app can now alert users of scheduled
events and alarms in the background, no servers required.
• Task finishing - If your app is in mid-task when your customer
leaves it, the app can now keep running to finish the task.
• Fast app switching - All developers should take advantage of this.
This will allow users to leave your app and come right back to where
they were when they left - no more having to reload the app.
What multitasking do you need that isn't in this list? You can't set
up faceless daemons, but jeezus, you shouldn't be doing that on a
phone. The difference between a daemon and virus is intent...
