Hello Been a while since I've posted - maybe 4 or 5 years. I just got a new macbook air. I love it, best computer yet. But, again - what the heck is up with OS and surfing (reading, watching, listening). I can edit, little after-effecting, write and my battery loses a few percent. But as soon as I start surfing - it ticks down wildly. Man it makes me angry!
