The Bamboo Project Management Suite features 15 different Web Parts specifically designed to keep projects on track and on schedule, including multiple calendaring and alert tools. In addition to these current offerings, a handful of new Web Parts will be added for free to the suite once they're released, including SharePoint Project Portfolio Dashboard and Task Master. Bamboo has historically had an ambitious release schedule, so it's fair to assume that users won't have to wait long.
The Bamboo Administration Suite includes a number of modules specifically focused on helping SharePoint admins manage their user base. These include a number of alert and password management tools, as well as Web Parts for user profile and account management. Like the Project Management Suite, other Web Part modules will be added once they're released, including the Site Management Solution Accelerator.
The Bamboo Ultimate Suite bundles just about everything that Bamboo offers, totaling about three dozen modules. This includes modules dedicated to supporting business intelligence, the administration tools included in the Administration Suite, as well as those included in the Project Management Suite.
Bamboo doesn't publish pricing on its Web site but it appears that each of these bundled suites are offered with a substantial discount. For an IT shop running SharePoint, they're certainly worth investigating.
