I gotta pay $50 a year for each user? I need some really basic e-mail here for the desktop users, nothing advanced really. Is the IMAP stuff really worth it in this case? They won't even be using the Google calendar, docs, groups, sites, videos that come together with this premium service.
EDIT: Actually think about it, I might be able to use some sort of calendar for everyone. For example, I want to send out a meeting request to everyone. And they can accept it and it sits in their desktop calendar. When it's 15 minutes before, it will pop up a reminder. What desktop software is good to go with that Google calendar service? I've used Outlook before, which was an all-in one e-mail plus calendar. But can't justify buying copies for all desktops in this case.
