Long press is the right-click of smartphones.
Yes. Maemo, for one, makes no bones about it: at the X windows level, a long press turns into an a right click.
Contextual knowledge, that's the phrase. With the iPhone, what you see is what you get-for better or worse. In Android, you need to press the menu button to discover the actions you can perform.
Also, I find myself constantly wanting to use Android's back button on the iPad. It's really become quite natural for me on my phone.
That said, I completely agree with the grandparent's comment about the menu button.
But the point remains, I also have a lot of annoyances with i-devices at the same time, compared to the two I prefer my HTC Desire, it would be nice to not be regarded as some type of idiot for possibly thinking that i-whatever arent the pinnacle of design that all things aspire to.
Edit: Add to this the long press of a list item, and between them, most actions are stuck behind an undiscoverable layer of UI.
