TrueCrypt. You create two passwords for the same encrypted space. One gives you data that you intentionally put there so it can be found. The other gives you your secret stash. It's impossible to tell the secret stash exists.

Sure! Like the Wii Vitality Sensor.

The PSP's browser is horrible, at least on the first gen PSPs. Half of the pages you try to browse to will throw a "Not enough memory" error. You type using an interface exactly like a phone's 12 button keypad (2 - abc, 3 - def, etc). There is no zoom in / zoom out feature. You get to choose from three "size options", all of which render pages incorrectly. The browser has tabs... but only three? Scrolling through a page is horrendously slow, especially while the page is still loading, which is also slow. Browsing the web on the PSP is a waste of time.

Do you have sources for either of those claims? I'm both skeptical and interested.
