I only use wireless when I need the freedom of not having a cable connected else it's almost always wired. Thus, desktops/printers/keyboards/appletvs are always wired and laptops are wireless (almost always only) when I'm mobile, etc. Mice are a mix but I somewhat prefer wired, especially for gaming.
Too many issues of batteries going dead, wireless networks being slow as hell at work, wireless networks somehow being intermittent for no apparent reason have sort of caused me to hate wireless anything.
