Theoretically, you can use a laptop without plugging anything into it, but if you're using your trusty lappy at a desk, it's pretty easy to go peripheral-crazy. I'm almost always rocking a mouse, laptop charging cable, and charging cable for my phone, and sometimes even a external keyboard. I know you Apple kids skew a bit more minimalist though. So whatcha rockin'?
And for all of you using desktops, I haven't forgotten about you; I just don't value your input.
