I haven't had any issues with my 40D or XTi, but it's because I baby them to prevent it. There is absolutely no reason Canon can't weatherseal the xxD series bodies. Fo $1200, it should be a given. Their competition is weathersealing in this price range in some instances... Lets see, my $249 GPS is weathersealed, my $200 laser rangefinder is weathersealed, my $500 rifle scope is weathersealed... Come on Canon, we love your products, but WEATHERSEAL them!!!
