As someone that hates checking battery levels, and replacing / recharging batteries when I'm in the middle of something, I really need to have a wired keyboard. Before I got this cable, I had to sit fairly close to my TV set (I have my computer hooked to the TV). Now, I can sit in a nice, comfy chair instead of the hard, cold floor. Life is good. Except when my cat jumps on my keyboard while trying to get on my lap.
