After study the specs from canon.co.jp, the main differences are :

300D has
1) NO Flash exposure compensation, that means you can't adjust the output level of the built-in flash
2) NO PC terminal, so
3) Can't update the firmare by user
4) NO custom functions

Of cos, there are some slightly differences.
300D has titanium-like plastic body layout vs 10D metallic body
300D has 2.5 fps vs 10D 3 fps
300D has max 4 shoots on continuing shooting vs 10D has 9 shots.
300D has battery life of 600 shots (no flash) & 400 shots (50% flash use) vs 10D has 650 shots / 500 shots.

Hope these information is useful to all EOS users or future EOS users.
