Offloading your apps sounds risky to me. It ends with "if the app is still available in the App Store" - not sure about you guys, but when MacRumors tells me something will likely be remove from the App Store, I jump on it.
IE, I have Floppy Cloud on my iPhone, the app that has a secret NES emulator in it - just put an NES ROM in Dropbox and the app will load up and run the game. I also have a "flashlight app" on my iPhone that actually enables tethering without paying your carrier.
