Hello, the basic point of this post is that I am seeking help to clear up certain questions I have as I will be making my first Mac purchase today after work. I've ruled out going for the Air because of the basic screen size of only 11", no optic-drive, and no ethernet input. 1)Thunderbolt - I'm still a little unclear as to just what Thunderbolt exactly does. Is it just another outputto hook your MacBook up to the Thunderbolt display screen? Seeing as I don't plan on buying the display screen, I was mauling over buying the 13" MacBook pro from either Apple or Best Buy. I am leaning towards buying it from Best Buy as the price is cheaper since it doesn't have the Thunderbolt drive (which since I won't be using it seems expendable). Other than that, I assume the product from either store is still equipped the same otherwise, except the new Pro's at the Apple Store will have Lion? Any input people have with more Apple knowledge than me would be greatly appreciated. Thank you!
