I've been a fond user of iStatMenus for a long time – I've been using them on my macbooks for at least 3 years; I generally keep autoupdate turned on for my applications on my mac – just do it automatically, I'll deal with the config changes later. I do this because I'd rather deal with the consequences of a broken config later...
...until someone does something stupid like this:
Bonus:
Clicking on the uninstall button leads to a screen where you're prompted to install an additional helper.
I'm slammed with work, so, I literally have zero clue on what the helper does...but, I swear to everything that's holy, if it's a reminder for me to try iStat Menus again in the future, I'm going to shit a brick.
