Well Good Luck Larry..
Dave, Like you I thought XP was/is great but was offered W7 ultimate at a great rate so went for it, To date( I am so going to regret this) but it has been fine..
I have heard that MS are talking about extending the support again for XP as it still accounts for over 40% of windows users with W7 at 45% and Vista 5% , if these figures are true or not is another matter.
Re W8 other than the abvious gripes I have not heard any true negative comments.
