When i was a sysadmin, I would have 30+ windows open at any one time.
Right now, I have 12 windows open. My minimum is at least 7:
2 wondows to 2 different pines for work/home email.
3 windows tailing access_logs for the 3 domains i host that actually matter.
1 tailing /var/log/maillog on my mail server
1 tailing /var/log/messages on my shell server
There used to be several more opened by habit, but then i got cvs-mode over ssh working correctly in Xemacs, so those are gone now...
