Email apps screen space used badly


I've just got an original X10 mini pro, previously had a BlackBerry. BlackBerry was perfect for email, X10 not so much.

Compare these pictures of the built-in email app, and the gmail app on BlackBerry - subject line and other headers are kept to a minimum at the top of the screen, leaving the rest of the space for the email body (looks good):

bb native email app:

bb gmail app:

And on the X10 - the headers take up the WHOLE TOP HALF of the screen, in both the native email app AND the gmail app! (looks bad):

x10 native email app:

x10 gmail app:

I thought these apps are supposed to be optimised for a small screen??!

Is there even a way to reduce the font size like I could in the BlackBerry?
Very unimpressed with X10 at the moment.
