I am buying my Macbook Pro from eBay, not from Apple. It is brand new but the eBay seller bought it from Apple before Lion was released so it still has Snow Leopard. Sorry for the confusion. Thank you to everybody who has replied so far. This has been very helpful. I think I'm going to upgrade to Lion as it seems the benefits outweigh the negatives. If anyone has anything more to add feel free.
