Andy van Dam. I organized events and chaperoned trips to Boston, the beach, museums, etc. I received free food and housing and had a very laid back summer. Research on multimedia databases. The project was fun, I got involved right away, and my code went into the final product which shipped a few months after I left.
Drawbacks are the loose guidance style and the area's public transportation.
So if you're willing to ask questions and either have a car or lots of patience with public transportation, you'll love working at Latitude. I worked at Iris Associates last summer. They develop products for Lotus, such as Lotus Notes, and the Domino server. The environment is nice, lots of offices and not that many cubicles, with free vending machines. The work I was doing was not that exciting, but it varies a lot with the team you are working with.
