I am killing my macbook. How?

1. Running on safari with 10 tabs/browser;

2. Virtualization on Windows XP in which:

    2.1 Five different document files in Word 2010 portable;

    2.2 Corel draw portable;

    2.3 Google Earth plus portable;

    2.4 AutoCAD with 2 files open simultaneously;

3. Google Sketchup;

4. iTunes

Oh poor, poor baby. Need an upgrade to Macbook Pro 13″. Oh, poor baby.

Or an iMac. *Hint hint*
