I believe that, during the past few years, IBM has made a certain amount of marketing mistakes, while Microsoft has been persuing clients with its usual aggressiveness.
The end result is that, while many companies using Notes are sticking with it, I hear fewer and fewer "wins" for Notes. In the meantime, reports of companies switching from Notes to Outlook are more numerous.
I fail to comprehend what can possibly motivate anybody to go from a robust, secure mail system to one that is patently riddled with security holes and requires a medical team on 24/7 alert, but this tendancy seems to real.
In other words, I think IBM is trying to kill the notion of Notes and replace it with Websphere, action which leaves the regular mail-wanting clients wide open to the influence of Microsoft. It is ironic that the company that owns the best product tries to kill it for database reasons, while the customers buying the best product have, for years, been doing so for mail reasons.
I may be wrong though, but still, how many companies have announced going to Notes/Domino in 2003 ?
As for books, I know of none, but several good websites are available :
notesdesign
Notes FAQ
and, of course, the official sites :
DeveloperWorks
Lotus.com
and the most useful,
the sandbox
Pascal.
