Lukas Mathis on the iPhone OS 4 Task Switcher

I found this article sitting in what I call my Tumblr Postbox. I should have included it in my previous post on iPhone OS 4 Background Processing. Here's what he says:

Basically, the task switcher is a tiny version of the Springboard that shows what amounts to a random selection of your apps


Say, you’re writing an e-mail while referring to a Wikipedia article; the task switcher allows you to quickly jump between the two applications instead of having to go through the Springboard, which would take a few seconds longer.


it seems to me that the few situations where the task switcher is useful do not warrant adding an entirely new way of opening applications.

This is almost exactly what I think. The case of rapidly switching between just two applications is interesting, so I have written about it in my next post.
