Not sure if it will affect the MBA or not. It definitely has a ton more ports. It actually has 3 USB ports! At the end of the day, it doesn't have leopard OS
I must say that I find it interesting how well Apple promotes/markets their products. Folks are so eager to know about their up coming products. If I didn't see your post regarding the u110, I wouldn't have known that lenovo was coming out with a new laptop. Good to see this forum promote some competing products
