I can't see anyone getting a subscription just to use these apps. These are more like addon apps for people who use Office already and happen to have an iPad.
Most people who are going to be using this are just using it for viewing / displaying anyway. If you don't want to pay just do the creating in Open Office or some such.
Depends on if you care. Most likely these employees are talented programmers, and the hiring environment is good right now. For those who have a bit of money set aside losing their job is an inconvenience at worst, a nice vacation at best. Especially if they were smart enough to start shipping resumes as they took their stand.
They also eat a shitton of disk space.
Windows 7 SP1, set of windows updates, is nearly 1 gb.
