I do not own a desktop computer and have not for nearly seven years. Before that, my primary computer was a Dell desktop that my parents bought me as a college graduation present that I augmented with a small notebook computer (at a time when such small laptops were just a novelty).
Even without a desktop computer, my life is full of peripheral devices. Laptops these days are so powerful that most can easily accommodate an additional monitor (if not two), and working in this way usually requires a detached keyboard and mouse.
Today, my mouse’s batteries died. Unlike my keyboard, which is solar powered, my mouse runs on rechargeable batteries, and I often forget to recharge them. When I do, I’m left with just my laptop’s trackpad and a sense of frustration.
