This is a great app and it's very helpful especially for phones with snapdragon processors like the Nexus One and Droid Incredible because you can open numerous apps at once but it does get to a point where the phone will slow a slight slowdown so you just open up the task killer, pick what you don't want running and boom your snapdragon is even snappier. The refresh rate of the app list in the task killer is very good but the MB available doesn't update automatically all the time but over all this is a very helpful application.
The only thing I would change about the app is the ability to select all/deselect all the apps on the list.
