Andrew - A webOS will only be as stable as the WORLD wide web is. Try getting that big project done for work when the ISP or other internet service is off-line for a day or the site that has the program your using gets a virus and is shut done for a couple of days to fix it.
The only program I have had that wasn’t at all easy to uninstall was Norton Antivirus. I had to search all over my Mac to find all of the related files left after using Norton’s uninstall.
