I just updated my Adobe Reader.  The only reason I do it is to patch vulnerabilities in their crappy ubiquitous system.

And, with the update it installs a shortcut to Adobe Reader on my desktop.

Seriously, now, why the hell would I want that?  How could this possibly be useful to anyone?  If I click on a PDF, it opens with Adobe.  If I click on the Adobe link, I still have to go find the PDF that I need to open.  Has anyone, ever, found a use for opening Adobe Reader directly and often enough to justify a shortcut on the desktop?!
