No need to ask the same question twice.

Answer 2

Usually operating systems have added changes over the previous one and I'm sure that is what Snow Leopard will have. It isn't due out until next year and many changes will still be made to it but you should be able to run it on a recently purchased MacBook. Sometimes the newer systems have only a few changes and some people opt to skip an OS before upgrading. It all depends on what the new things will be and Apple will not leak any secrets until it is ready. By the way, it IS a new OS.
