This app is great. It allows you to make the Window Animations and the Transition animations faster. (So that when you switch to landscape mode, it snaps right away just like an iPhone. I've noticed some lag before installing and switching this on.)
It will also give you a read out on your battery usage, similar to what the Moto Droid comes natively I think.
