I doubt any tears will be shed for Notes
My medium-sized multinational company just got rid of Notes 2 years ago...for email. There are still some business-critical functions carried out via workflows embedded in Notes databases. But I'm sure the owners have spent this time rebuilding them...I hope...
I can't believe it's managed to hang on this long. I never really liked it, but in the dial-up days it was very handy to be able to take your entire mailbox with you and work offline as if you were connected. Outlook didn't get that for ages. The positive thing is that now that's in the hands of some Indian outsourcing firm, we're never going to see any NEW deployments. Maybe that will finally be the thing to kill it...just keeping it on life support for the one or two holdouts.
