I'm considering going down to Baltimore just for a day, to visit the exhibit hall. There are several interesting looking free CME classes, and a lot of new stuff to check out.
You can find a list on their website.
The list of exhibitors is here. Each has a description of what they have, and most of them have links to their websites. There is a symbol to show which are new exhibitors.
There is a list of free classes in the exhibit hall here. The whole list of sessions is searchable.
I'll come back and note what I find most interesting when I get a chance.
