I love love love your articles and really appreciate this site, but you're flat-out foolishly wrong in your dismissiveness of the Dashboard.
Yeah, at default, it's of little utility (though I find the calculator handy on a weekly basis), but there are two utilities that reside there that prove invaluable to me in my life as IT support to a wide array of users and machines.
Maintidget: at a glance, you can see if the daily/weekly/monthly cron jobs have been run. Oft-times, the daily and monthly have run, but you'll see the weekly hasn't been run since last August. A quick press of a button runs the scripts and bam, lots of niggling issues are resolved.
iStat Pro: another "at-a-glance" that serves as one of the first things I check when someone has issues. IP address (does it have one? two? is there an external or is it self-signed? etc), temperatures, process % (sure, activity monitor gives me that, but this is a BUNCH of info at once glance), storage capacity (used/free -- in this age of SSDs and people with too much stuff, a full SSD (or one nearing it) slows dramatically), memory use (see above re: activity monitor).
So, with the click of a button -- or swipe sideways on a trackpad -- I get a quick overview of someone's system and can proceed with far more knowledge than I had seconds before. Swipe back and all that data is hidden away, waiting. That ain' useless.
Frankly, I'm fairly agog at this minor snit fit you threw over something so innocuous and potentially helpful. Perhaps an article listing a few useful widgets would've been of more use?
