Mine has 31 currently running?!?! WTF??? Some are running twice like AK Notepad and The Weather Channel? I'm thinking 2.1 is having issues managing applications. I keep hitting my end all widget and it's always like 20+ apps running. So much for the extra ram, things just keep restarting for now reason!
EDIT: After more playing around, it looks like the Back button does not close applications like it does on the G1 and MT3G. Great, better get used to using the Task Manager Widget or nothing will close!!!
