Mostly I browse the web, listen to music and use IMs, however I do play the odd game. I've attached a screen capture of my general usage (when not playing games). I'm new to Mac so don't fully understand it yet. Early 2011 MBP 2.3 i5, 4GB RAM and 320 HDD. Also considering putting a 256 Crucial M4 SSD in the MBP.
