What stuff do you have on your home screens? If you have a lot of widgets that get updates, such as stocks, twitter, etc, that will burn up some memory. I only have the clock with weather, stocks, and program icons on my screens.

Also, how do you "exit" programs? Do you just hit the home key, or do you use the back arrow key, until you are back at your home screen? Hitting home leaves programs running in the background, while using the back button, in most cases, will close the program you were using.

I have very little lag on my device using the above methods.
