Linq would have made forming the queries a bit shorter, but not really easier. When you look into linq and like it it saves you typing a few lines here or there, but it definitely is no difference from a strategical point of view. If you transform a lot into xml linq can be a good help to save some time, but if you dont you will mainly only experience linq as a way to make the syntax a bit easier. For an existing project i would not recommend suddenly inserting linq code, but i suggest you take a look at the msdn articles, they give good examples about what you can do with it, maybe you will use it in your next project if you like what you see:
