1) Less code -- you only have to check that the user's selection
   is sane once.

2) Cleaner code -- you can abstract checking the user's selection
   to your Session class, eg. in a set_style_sheet() method.

3) Fewer cookies to send -- speaking for myself, I hate sites that
   send a separate cookie for every little piece of information.
   I'm peevish and tend to start rejecting cookies after receiving
   2 or 3 from the same server, assuming I accept any in the
   first place.

4) More room to grow -- what other per-user state information are
   you going to want to keep in future?  With session management,
   it's just a question of adding attributes to your Session class.
