Of course "people don't multi-task" really meant "we won't multi-task until we have the technology ready to do so" but this is what I found as a more funny "Jobsism":
Q: How do you close applications when multitasking?
A: (Scott Forstall) You don't have to. The user just uses things and doesn't ever have to worry about it.
A: (Steve Jobs) It's like we said on the iPad, if you see a stylus, they blew it. In multitasking, if you see a task manager... they blew it. Users shouldn't ever have to think about it.
WinMo 6.5 did away with the task manager and Android has never had it. But do you want to know what type of apps people are most downloading for these phones? Task Managers. Here's the thing - no matter how much you think you know about how a user should use their phone, each user will be different, and many will want control over their own phone. If it's in the SDK for the iPhone 4.0, people will download task managers like crazy because, Steve, people just like to have control over their resources.
As for the stylus, I tend to agree except in cases of folks who use a tablet for note taking (and drafting) and not an internet device. I can't write nearly as quickly or as accurately on a touch device with my finger. So if the stylus is used for writing, I support it. For controlling basic functions, completely not necessary, and I think most device manufacturers and software makers get that.
