Just watched this (thanks John!) and realized that unlike other smartphones, iPhone applications either politely quit or are able to be minimized to such a degree that they are always running. When you watch this, there does not seem to be much difference between returning to an app (state is saved) or opening it fresh – which seems hard to do with the exception for the iPod function which seems to start at the top of its menu.
Pretty slick. I’m far too used to having to choose whether I want an app to remain open or if it’s ok that it quits when running Symbian and this looks like a nice change.
This is actually the same way Windows Mobile devices have always handled apps – they don’t really close, just move to an idle state in the backround. If the device needs more memory, you app gets sent a notification, where (as a dev writing the app) you try to free up memory or quit if necessary.
It’s pretty slick.
Good to know – I’ve steered clear of the WM5 devices but have been intrigued by some of the newer HTC ones…
