Stan - it really is important to get that upgrade to 10.1.
It's about 15 quid by post but apple resellers will have free copies to give to personal callers.
I know you didn't get anything you'd regard as a manual with the computer but there was a a very important set of coupons amidst the bumpf. Its a card with 3 Mac OS Software coupons allowing you free upgrades. Set off hotfoot with those coupons this week before they run out of the new discs.
