It basically saves the pain of typing \ or {} after all commands.
Suppose I have
\abbreviation {ABC} {Some abbreviation}
As we know \ABC is an abbreviation.
Notice that there is no \ or {} after \ABC. Normally tex will gobble
this space. With xspace one can use something like
\def\ABC{Some abbreviation\xspace}
and it will intelligently decide whether to keep a space or not.
Adding this feature will not effect existing documents.
More details and deinition from xspace.dtx
% |\xspace| should be used at the end of a macro designed to be used
% mainly in text. It adds a space unless the macro is followed by
% certain punctuation characters.
% After |\newcommand{\gb}{Great Britain\xspace}|\\
% \newcommand{\gb}{Great Britain\xspace}
% |\gb is a very nice place to live.|\\
% \gb is a very nice place to live.\\
% |\gb, a small island off the coast of France.|\\
% \gb, a small island off the coast of France.
%
% |\xspace| saves the user from having to type \verb*+\ + or |{}| after
% most occurrences of a macro name in text. However if either of these
% constructions follows |\xspace|, a space is not added by |\xspace|.
% This means that it is safe to add |\xspace| to the end of an existing
% macro without making too many changes in your document.
%
% Sometimes |\xspace| may make the wrong decision, and add a space when
% it is not required. In these cases follow the macro with |{}|, as this
% has the effect of suppressing the space.
%
% Note that this package must be loaded \emph{after} any language (or
% other) packages that make punctuation characters `active'.
