Yes and no. The first filters out all inputs that are not checkboxes
before returning the jQuery object.
The second returns all inputs, including checkboxes, and then filters
out those that aren't checkboxes.
The difference is that with the latter, you can operate on the
filtered result, for example adding a css style, and then chain .end()
to revert to the original selection of all inputs and work with them.
