Sadly my Grandma is one of the UK's 1.4%, but she can't really help it - she still uses Windows 98! It's the latest version supported on that system. Now in her 70s I can't imagine her buying a new computer anytime soon, even so it means that things like Facebook and Youtube barely work at all. Not that she's often on either.

Since I upgraded from XP to 7 last week I've also moved finally from IE to Firefox. It's the former's inability to load Facebook Timeline correctly that finally did it for me.
