Theres an interesting poll running at the moment on the sidebar of
Notestips.com, about how long people think they'll be working with Lotus Notes/Domino. My gut reaction was to go for the 0-2 years, which seems to be the most popular choice so far (68.8% at the time of writing this).
It's really a shame that so many people are thinking hard about making the switch away from the product, and so soon as well, but in many ways I don't blame them. Obviously there will be sites running installed Domino architecture for a lot longer now, but I guess it will be like working at a Netware 3.x shop during the time when people were making all their NT Migrations - the only work going will be maintainance work, or helping people migrate to something else.
