For me, and I am more computer savvy than the average end user it was a negative experience.
You can imagine then how frustrating it is for her. She's already had to reinstall the OS!!! I'm trying to help, like with setting up email, but the system has a new email client called Windows Mail that no one else knows about. If I can get XP installed on her machine, I'll bring her over to Mozilla Thunderbird which I use.
