I've had the luxury of making my own Mac computing arrangements for both work and play over the last decade or more -- so I haven't really used a version of Windows since 95. Anyway, I'm about to buy a new laptop for my mom and was wondering what I should do about the OS -- is Vista really bad enough that I need to go get a copy of XP instead? She's in her 70s and uses the PC pretty much exclusively for email, Flickr and Skype video chats with the grandkids. Simplicity and stability are key -- as she's also 8,000 miles away and tech support is me. And no, she doesn't want a Macbook.
