Macbook Air so slow I bought the Macbook Air on August, and I have to tell you, it's a piece of crap. It's so slow and it's painful to browse the internet or write stuff on Word. The processor is a 1.7 GHz Intel Core i5, and I was wondering if I needed a better processor? The memory is 4 GB and it's only like a tenth full so that's not the problem. If this is in the wrong section, forgive me, but help me!
