Lotus Notes stats
To date IBM state that they have sold over 140 Million licenses for Lotus Notes, they don't say how many are still in use / paying annual maintenance but I'd imagine it is a lot of people (10's of Millions).
So something like this is big, big news for a lot of major companies - companies that could very easily go out and buy many thousands of new phones for their staff at once. So it could be big news for Apple as well - the first major corporate switch to the iPhone will be headline news.
Here are some facts on Lotus Notes:

As a market share leader, Lotus Notes and Domino ranks second in the integrated collaborative environments market based on worldwide total revenue
Lotus data indicates that approximately 97 percent of Lotus Notes and Domino customers are on the 6.5.x release or higher
Lotus Notes and Domino are supported by over 10,000 IBM Business Partners worldwide who have thousands of integrated solutions running on it
From 2006 to 2007, the number of IBM Business Partners delivering Lotus solutions more than doubled
Market share numbers are anywhere from 40-43% of the worldwide collaboration market and growing depending on the analyst performing the study. Some companies have both Exchange and Domino and are licensed for both so there is overlap. Microsoft licensing agreements for Office sometimes include Exchange and Outlook licenses which are counted as valid by Microsoft when in fact those licenses are never used because they are sold to a customer using Notes and Domino. Those licenses remain sitting on the shelf but MS reports that company and an Exchange customer.
Lotus developed iNotes in late 2007/early 2008 and has in beta as a part of Domino 8.02 due for release in Q3/2008 the new iNotes interface for iPhone. Lotus was given the developers toolkit by Apple this just this Spring and developers are evaluating ways to add more Lotus functionality. Anything Lotus develops has to meet business enterprise ready requirements and security concerns. Since Lotus Notes is the world's largest installed Public Key Infrastructure we have to make sure that any application developed for iPhone has security in mind and cannot be compromised. Our customers have that expectation of absolute security of the data and the PKI inside Notes.
Lotus Notes 8 is based on open-source Eclipse, integrates with Google Gadgets and includes integrated instant messaging and awareness, includes composite applications, and allows anyone to change the look and feel of the interface anyway they desire. You can even change it to look like Outlook. Notes 8 has hooks into social software and other products. The Notes 8.5 Mac OSX Beta is available now for downloading and will be released in Q4/2008 with Domino 8.5. Lotus Symphony for Mac (Open Office based document, presentation, and spreadsheet editors) will also be available for no charge by the end of the year. Lotus Quickr and Lotus Connections (social software) fully support Safari on the Mac. Many of the other Lotus software products support the Mac since our customers are all looking at adopting Mac OSX as an alternate OS to Windows. Gartner reports that 56% of CIO's are looking at other OS options like Linux and Mac now.
Many IBMers are now adopting Macbook Pro laptops as an option for some IBM divisions and the Mac has quite a devoted following inside Lotus in particular.
