when i first got the eris, i was having pretty bad lag by the end of the day, so i installed TasKiller. now, at the start of the day after i go through my routine of shutting stuff down when i turn the phone on after the morning reboot, i have 82-85 free. By the end, thats dropped to anywhere from 60 to 75. I've read in a few places that there's an autokill, that the android os learns what to kill and what to leave alone, and to let it do its job. other places, just the opposite. so which is it? should i delete taskiller and let the OS do its own thing? also, i force stopped gmail earlier today, in lieu of using a bookmarked gmail-mobile as it will show pictures where the app wont. will this force stop remain after reboots, or will it come back after a reboot and need to be stopped again? and is there a way to remove this blasted footprints thing? it eats memory (not much but a bit) and i dont even know what its for and doubt ill ever use it, not knowing what it is.
