If you haven't already visited the updated Delphi Tools and Components page, do it now. The page now has links to a page of Delphi 2010 compatible tools and components, the ability to search the tool and component directory, and three featured tools.
The initial three we chose to feature, based on the feedback in our earlier survey of Delphi users, were DevExpress VCL Components, TMS Component Pack, and Modelmaker Code Explorer.
There are also similar pages for the other products in the RAD Studio family.
