Yeah. If you need to unlock doors, then you need keys. But you don't need a flashlight all the time unless you are a security guard or something.

We might as well be talking about purses.

That's what I thought, until I started carrying one. Now I use it all the time for mundane tasks such as finding something that dropped under my car seat, plugging in an ethernet cable under my desk, rummaging around in the back of a closet, and so on. It really makes life easier, especially as I find my night vision isn't as good as it used to be. LED lights and Li-ion batteries last for ages, so it's hardly an inconvenience.

I find the one built into my cell phone adequate for all of that. It's brighter than the $3 filament bulb flashlights they sell at Wal-Mart, which people considered adequate for decades. I have a real flashlight (uses the same Li-Ion pack as my Bosch cordless screwdriver, 8+ hours continuous use) for something like walking at night; I don't need to carry that all the time as the phone light is plenty for all spontaneous type situations you've mentioned.

Well, it's nice to able to light up a room when you need to. But to each his own.
