Its "popularity" is not a reason to add any PRO. It has gained its popularity because of high level making. Most of that popularity was at the time it included all commercial products such as Acronis, Paragon, Symantec, etc.. It's only after version 10.4 that those apps were dropped out.
There is also no reason to qualify it in CON only because it's outdated as it was discontinued years ago.
For users that still run Win XP or Win 7 it's still relevant in most cases. You just have to realize that it was built at a time when common systems was based on x86 architecture, not x64 one.
