Suprisingly, Windows is less demanding of my system compared to Tiger, since I have yet to recieve my 2GB of ram. 512 is just not cutting it for Tiger, and Windows is built for all the crap boxes of the world so it's no suprise that it copes with small amounts of memory.
Granted, I lose basically every feature that I can't live without by using the Windows partition.
Then again, all I use it for is games. Like the windows operating system was meant to be used..... like a toy.
