it wasn't a big deal to theme GTalk.. you just edit it's resources and you're done..
but theming GMail displays the power of CSS.. you just edit the local CSS to override the site CSS.. of course it's simpler than theming GTalk.. but that's where it becomes better :) one can very easily write a GMail customiser which churns out a local CSS to customise their GMail LnF.. (in fact I'm plannin to write one ;) )
simplicity rules...
