forget about freedom of choice for apps for just a moment, I just want to be able to set my iphone to never autolock. WTF apple, it's connected to a power source and yet you insist on locking it every 5 fucking minutes.
My iphone is going on ebay once I see an android phone come to market with decent hardware. My #1 gripe with the iphone is I can't develop apps and put them on just my phone, without paying 99/year. I'm just not interested in the app store. Android lets developers install apps on their phone for free. Though I suspect apple will loosen it's grip as android/pre/blackberry gain traction and maybe we'll see background apps and other features.

I think part of the problem with automated light switches is they're high liability and low volume. It burned down your house? oops sorry.
