Teger what will you be using your computer for? Most people that dont use their computer for work (photo/video/graphics/games—computing intensive things) dont need a pro. Plus, the air is drop dead sexy. Lastly, have you ever used an SSD? The boot time and basic operation of the air is so much faster with the air. Certainly you're getting much less storage place, but many of my friends have gone Air lately and never looked back.
