We've covered RedEye's IR dongle for the iPhone a few times. Originally, it was introduced as a complete add-on for the iPhone that allowed you to control any entertainment center reached by infrared. Over time RedEye has pushed to simplify the unit more and more, instead providing a cheaper and smaller experience.
Now the company has done that again. While the original iOS app offered a lot of different customization and functionality, the new RedEye mini app offers a straightforward TV remote experience. It's free, like the full app, but instead of having to customize everything exactly the way you want it, you can get a simple channel changer and volume control to use on your iPhone.
It's been interesting to watch companies like this learning what Apple already knows: while power and customization definitely drives part of your audience, the real way to sell a product is to make it easy to use for anybody who picks it up. I'm sure some people prefer the more complex, self-designed system (myself included), but if you want to aim for a larger market, simple and easy is often best.
