I kind of get the point of these keyboards for mobile devices or home entertainment systems. But they really don’t make the slightest bit of sense in a regular setting, i.e. on a desk. They’re not being moved around like a mouse is, so there is usually zero benefit to not having wires, while there are a lot of downsides: battery requirement, interference when several people use wireless input devices, signal strength problems (my wireless Logitech mouse doesn’t work through my 1-inch wooden table top, I had to move the receiver to the front USB ports), and of course the mentioned security issues. Which is why I don’t get why manufacturers almost only push the wireless keyboards anymore. Simply because of the higher profit margin?

I’d never buy a wireless keyboard, even though it gets increasingly hard to find wired ones with at least the slightest convenience features (I like having a few media keys to at least play and pause my background music player). I mostly go for OEM keyboards now, which are not meant for sale to end customers, but PC manufacturers and such. Apparently at least the professional buyers still have some sense.
