Wow. A lot of discussion over my simple program

Thanks for the suggestions. I thought about adding something to prevent quick lock/unlock cycles, but it didn't seem worth it, as I didn't have any trouble with it, and it might not lock/unlock when you want it too (when slipping the NIT out too check the weather quickly). Right now it also turns the screen on when uncovered - maybe that wasn't a good idea.

The program was designed for people (me) who put the NIT in a thick cover (like the one that comes with it) when not using it - the light sensor reads 0 lux in all but direct sunlight when in the gray cover.

I also suggest anyone that uses it read the web page or check the source code (it's short).

There's two ways to disable autolock: either use the lock button or slide out the keyboard.

I consciously tried to avoid any configuration options to make it easy to use.

I also hope it works as a proof of concept to Nokia, so they include something like it in later OSs.
