I agree. Letting the user know imidiately that "yes, I know you asked me to
do something, I'm working on it" is important for the percieved speed of an
application.
If an app starts animating an image, writes a message in a statusbar or
something similar as the *very first* thing it does as soon as it registers
user input, then the user wil percieve that application as being "fast". 
If the app just starts doing it's thing, and then when it's done tell the
user that "now I'm done" - even if both applications took the exact same
time to get from start to finish, the first app will likely be percieved as
being faster than the second one.
