Any reason to stick with ie6 over ie7

[freebooter]

I have just reinstalled XP on my laptop and it installed with ie6. I did have ie7 and wmp11 installed before and had problems with wmp11 so am leaving that off but I am not sure about ie. I don't use it much, just very occasionally when a site doesn't work in opera. Windows update keeps nagging me to upgrade. Is there any good reason not to? (remember I am still on XP)

thanks

Thanks for the replies. I think I will update just to get rid of the nagging reminders
