Don't see why. With Android I can set different tones for each different email account, Twitter and Facebook account. Each time a phone notes, I know if its GMail, Hotmail or Twitter. On iPhone, every freaking notification comes with the same tone. You don't know i f its the news app, or if its Facebook or an SMS. Oh yeah, not to mention every new notification displays over the previous one, leaving you with no manageable order how to handle each notification individually.

I don't think Apple even agrees that there is nothing wrong with the iPhone notification system, considering who they hired from Palm.
