It's funny you mention InfoPath. I know of at least two multi-billion dollar companies that have significant amounts of development time tied up in InfoPath. All of its still running, with the plan being to replace it over time.

Still just sitting there running.

No need for pardon's. Use what you like that gets the work done. My instinctive flinch is different. We all have them. That's the thing, I don't want you to switch. I don't care. I love open source software. What I am saying is that they have a lot of effort built into backwards compatibility. And those solutions may not be the latest hotness, but you can still run them.
