Even though the CPU of new macbook air (2.13GHZ) is a bit lower than that of macbook pro(2.26GHZ), however, the 128GB SSD HD performs better in mba than the traditional HD of mbp. On the whole, which performs better? Some people told me that even though the new air is of great improvement than previous products, it still could not compete with the lowest macbook pro!!! Is it real ???
