I've never liked any of the tracking devices that most laptops are equipped with. Even with an inordinate amount of tweaking through whatever utilities are available, I've always resisted using them whenever possible. The mouse has undoubtedly done its fair share of cumulative damage to my wrists over the course of too many years spent entirely at keyboards and spending at least some of that time standing at workstations and typing around people while they refuse to move.
An Aside: Speaking of which, if you work for a company that I also work for and need my assistance with your machine and then suffer under the delusion that I'm going to dictate instructions to you while you putter around and click pointlessly be prepared to have your stupid ass shoved aside
Aside aside, I've often embarrassed myself by being a fumbling moron when forced to use a trackpad in front of people who spend less time in front of a machine and consequently much more comfortable using the trackpad (don't ask for evidence of correlation here because I have none other than violent and irrational dislike). In the interest of proactivity, I've decided to try working exclusively with the trackpad on a couple of my laptops for a few days. Hopefully I will learn something from the experience and won't just fire up Ion to avoid using a pointing device entirely.
One immediate and happy discovery is that Chromium is a more mouse-optional browser than I imagined. The point wasn't to abandon mouse use entirely, but I feel like I'm already moving towards a less mouse driven use of the browser. I don't know if this is a good thing necessarily (less wrist fatigue! yay!) or moving towards terrible-ness (I can only browse the web using vi keybindings. Also, get off my lawn!). We'll see if I don't abandon this experiment altogether.
