It's just to frustrating for me to have to reinstall everything, I had about twenty programs installed last time I reformatted.
I've never got that many, I'll install something to use it and then when I'm finished it gets uninstalled or deleted with the format.
I just turn on xbox or something while I wait, watch a bit of tv here an there, shout hurry up at it when load bars pause for more than 3 seconds.
