My logitech mouse is connected via wireless RF not IR, no line of site and the link distance is quite acceptable too. The keyboard mapping has nothing to do with mouse IR control of an AV system, I just mentioned that as it is a nice feature as well.

As far as voice command and conversation features, I was of course refering to the softwares capabilties since that is what enables mouse control of my AV system.
The software is a voice enabled artificial intelligence, thus you can have an intelligent voice conversation with it if you have a microphone attached to your HTPC.
Anyway, I suggest you go troll somewhere else as you are obviously just here to argue and have absolutely no clue what you are talking about. Maybe you can convince a few naive non-intellectuals on some gutter forum into blowing $600 bucks on a remote control when they already have a computer connected to their home theater system, but most posters here are a smarter than that.
