I push my computer very hard…

1. Average around 500 emails a day.
   


2. Usually have no less than 10 windows open after an hour of using it. Average probably 20 during most of the day.
   


3. My average memory usage is 300 MB.

I do try to avoid some performance hogs. For instance, I am not running a firewall. I use Trillian instead of ICQ, AIM, MSN, mIRC, and Y!Msgr for doing instant messaging.
