Not having to connect to The Internet in order to use software, which inherently does NOT need the Internet--except for the anti-piracy checkering feature.

I guess that really makes me miss the days when companies didn't treat their customers as if we were all pirates out to steal everyone's IP. For example: I have a program which got confused when I moved My Documents to a NAS, and I had to re-register it. Apparently My Documents didn't completely transfer all the real folders (Windows lies) and I had to do it again. I didn't even move that program's data the second time, and it once more failed its piracy check. I stopped using that version of the software (went back to previous serial-numbered version) and I'm not going to buy an upgrade unless I see evidence that I can use it with confidence that it will not fail me again. The data it keeps is too important.
