I like having the application on my machine so I can use it without permission or contact with the remote server, at least after licensing is completed. I find myself working offline more than you might imagine, and I also run desktop software that is 10 to 20 years old pretty regularly. I shudder to imagine what will happen to today's generation of SaaS software once it is past commercial viability. Probably it will be lost forever, unlike stuff from the 90s and 00s that still runs fine.
