I’m a bit surprised that they did not mention any Norton / Symantec product in the list because those top all of the mentioned ones in my opinion. It is also interesting to note that all five mentioned programs have lightweight alternatives that provide most of their functions.

Adobe Reader can be optimized to load blazingly fast or users can use Foxit or a similar faster software. Apple’s iTunes can also be replaced with lightweight software except for the iTunes store as far as I know. Real Player has the Real Alternative software, Opera and Firefox are great browsers that are in many aspects better than Internet Explorer and Microsoft Outlook can be replaced by Thunderbird although it is missing some features (exchange server, calendar).

I would probably remove Internet Explorer and Outlook from that list and add Norton / Symantec programs instead. Which programs would you add to the list ?
