Wires are dependable. Wired items (earphones, keyboards, mice) are always ready, always available. Several times I've tried bluetooth keyboards and mice, only to throw them away in frustration as the batteries go flat in no time at all. Logitech Keyboard: "Up to 6 months of life" - bullshit. I'm lucky if a set of batteries last 2-3 weeks. My USB keyboard and USB mouse are always available. So I don't need to think about that extra problem at all.
