Just to put some more sticks on the fire, one of the things that bothers me the most about the iPhone is the fact that the OS is, in my opinion, way behind both Android and Maemo when it comes to information presentation.

When I use my phone, I am basically after two things.

1 - The device must have the neccesary features and software that I need and want.

2 - The device must give me information and make my life easier by presenting it for me, rather than having me having to actively "ask" for it.

I want my phone to tell me what the weather is and I want it to show me RSS-feeds and I want my Facebook updates presented as well. Maemo and Android does this by presenting me this information on a desktop that supports both widgets and shortcuts. The iPhone only gives me an icon grid that made by brain die of boredom after 3 weeks, even with the various iconsets and themes you can install. This means that I actually have to open the weather app to get the weather, I need to open the the RSS app to get the feed and I need to open whatever Facebook app the iPhone has in order to do anything..

With the iPhone, you have to get the information you want, while with Maemo and Android, the information is presented to you in whatever manner you want. A proper desktop is probably one of the most important interface features on a (touch screen) device today. The iPhone has fallen behind on that area and in my opinion, it seriously cripples the user experience because of it.
