The Sam Adams glasses seem popular, I'd like to try them some time. It seems that most people are happy to drink most of their beers, session-style, from a standard pint glass (or variations, more fluted ones, etc) or a mug; for serious tasting, or barleywines, or Belgians, they'll often go for a tulip glass, brandy snifter, various curvy goblets, that do better at giving you the aroma and maintaining the head. There are a lot of neat pics in the thread I linked.
One thing that is generally not recommended is putting the mugs in the freezer. It kills head retention, and to me it just makes things too too cold to taste.
