Till I agree with you and would never use any kind of internet explorer
old or new
Just talking about website statistics, 25% of XP users is still a lot.
More, in my case, as you may read from other posts of mine, I use SSL mainly for facebook apps, ssl is mandatory, and my websites links are masked by facebook app urls, the user actually never sees my SSL URL
ort, they only see the facebook url. Facebook apps are used all over the world where many, many users still run XP and or IE8.
