This list discussed this topic a couple of weeks ago.  Recklessly
simplifying, it boils down to this: By using new-style classes, your objects
inherit a number of pre-defined methods and properties which you would
otherwise have to write yourself.  Ceteris paribus, a new-style class takes
up less memory than the equivalent old-style class (there was some wild
surmise about why that should be, but it's not important now.)  Finally, it
appears that Python 3000 will require new-style classes, so you might as
well get used to them now.

For your program, the only difference is that instead of defining a class
like this:

class Thingy():
    pass

you would write this:

class Thingy(object):
    pass

Not much downside, I'd say.
