I'll repeat what I commented on Mashable... the "most useful feature" (which is "freeing memory" not "showing free memory, that still works) generate a lot of crash reports.<p>Whenever you hit the "free memory button" iStat fill the memory of the device until it receive a "low memory warning". In the mean time all background apps are zapped which includes Mail, iPod, ...<p>I can see why Apple is annoyed to receive crash reports because an app willingly force theirs to crash (gracefully).<p>Still, iStat is a great app, beautifull and functionnal. I personnaly won't miss this feature.
