Boy, is my face red.
I got my discussions mixed up. I thought I was responding over in one of the W8 discussions. Try re-reading my comment assuming I'm talking about switching from W7 or XP to W8 and it might make some sense.
Of course, that isn't what we were discussing. Obviously there is a potential to save some money replacing ongoing licensing costs with software available at no charge.
I'm gonna plead 'Senior Moment'.
