There will be no backwards compatibility of Apple Pay because Apple wants you to buy an Apple Watch for that. Also I would assume that iPads will not get NFC, because they don't have Passbook. What would be nice is if Apple allowed people to pair iPads and/or Macs with the Watch instead of an iPhone. That way users can take advantage of all of the features without having to have a smartphone and data plan.
