Correct, the 767s with the 'old' club seats now feel very outdated.

The middle seats in either a 747 or 777 are great if you're travelling with someone you love (or even like) - with the privacy screens up it's like a little playroom in there. They're rubbish if you're with a stranger, unless its Angelina Jolie, or if you're with a heavily overweight, malodorous colleague.

The UD aisle seats on the 747 are prone to wobbles as other pax and crew wander about - the UD floor has much more flex than the main cabin floor.
