I completely agree.  I find that especially older people simply do not understand computers or even the concept of multi-tasking.  The iPad has been getting flack because it is basically just an iPhone and can't run multiple apps at once.  Yet the problem I see is that a lot of non-tech people don't really seem to understand the idea of running multiple programs at once.  To them the iPhone style of opening an app, using it, closing it, and then opening it to see it in the state that it was in when you closed it makes more sense.  As long as app launching is kept extremely fast, almost instantaneous, it is no inconvenience either.<p>This is just one small example of the way the iPhone / Apple techniques seem to work well for people because they are simple and easy to use.
