Funny how they mention iTunes as one of the "key components" that are restored first, whereas Visio, Project, Adobe application are relegated to a second round.
Presumably iTunes is part of their base system image for all workstations, along with Office, Firefox, Adobe Reader, and the like. In other words, a basic set of software to handle standard officework tasks. iTunes is free and IT would probably rather distribute it everywhere than have people trying to install it themselves (or calling the helpdesk to get someone with administrator rights to do it). They then offer additional applications on an as-needed basis to individuals and departments with specific tasks. So the designers who do print publications and the faculty who teach digital art might get the Adobe suite, while people in Facilities who plan construction will get Project. This keeps licensing costs down and simplifies systems according to their uses.
Generally you're going to keep your base images in SCCM limited to software that's only infrequently updated. Otherwise somebody has to update the entire image every time an update gets pushed out. Instead, you package them up and deploy the apps on top of the base image at install time. It takes a little longer to deploy, but it takes less admin time to manage since the actual installs are automated anyway.
Not hard to imagine. The others likely have specialty licenses and so aren't as easily distributed to everyone. In addition, Adobe software itself wasn't working earlier ;-)
