Actually, despite your sarcasm... I do not suggest it. In fact, I'd state that serial tasking is perhaps the worst way to experience any tasks on any device.

But, I did want to give you the knowledge of how limited the experience is on the iPhone. Your prior statement was slightly lacking because of the oversight of Fring.

I won't go into details about how many times each have/have not been updated for each of the platforms; let's just hope that the N900 gets more updates than the N810/Maemo 4 platform for Skype and Fring.
