Drawbacks or benefits that are particular to the software

Consider two pieces of software that you use or want to learn to use (you cannot consider Word, PowerPoint, or Excel® for the purposes of this assignment). Is the software you chose proprietary, or is it open source? How do you know? If it is proprietary, find an open-source alternative (For example, if you are looking for a proprietary word processing program, you might choose OpenOffice Writer.). What are the benefits and drawbacks of using proprietary software? What are the benefits and drawbacks of using open-source software? Are there any drawbacks or benefits that are particular to the software you wrote about?
