That's what I used to do, when I was a Windows and Linux user, because the trackpad on PC laptops was intolerable to use for more than about one minute (and I could never get the hang of trackpoint).
Developed a habit, like checking that I had my keys and wallet, when taking my laptop anywhere. Grab the mouse, grab the power supply, throw them in the bag, because the trackpad was always nigh-unusable and the battery life was only good enough for hopping between outlets unless you had a (charged!) extra battery to carry along.
Took some time to break those habits after switching to Macbooks, where neither was necessary unless I'd be away from my desk more than a day. Unplug laptop, pick up, walk away, don't think about anything else. Go figure, a portable computer that lets you treat it like it's portable.
