We are fortunate to be on great terms with both of our main competitors in the ASP.NET user interface space. Below are a couple of photos with the guys from Infragistics and Telerik, taken after the DevConnections conference in Vegas last week.

We did a little jersey swap "after the game", so I am wearing Telerik's shirt. Nice shade of florescent lime, I think it looks really flattering on me.
Seriously though, the fact that we compete vigorously doesn't mean that we can't get along. People who are confident in their abilities and their products have no problem being open and approachable by anyone. Each of our companies has its strategy for adding value to the platform (I will blog about ours shortly), but I think that ultimately all of our customers end up benefiting from having such dynamic companies innovating in this space.
