Hello - if you are planning on ordering OS X Leopard, I would ask that you consider pre-ordering it through our Amazon affiliate link. This is one of the few places that you can place a pre-order at this time.
I got one this week; It's like facebook and twitter had (CONSENSUAL!) sex and had a baby that grew up to be a lady's man... and an olympic track star. It runs at optimal speeds like their search engine and Chrome, I like it.
