I am using MacBook Air from last one year and its performance is really awesome. I use it for video editing, photoshop and music production and it helps me alot. I works wery smoothly. No hanging amd faster rendering. Its battery backup is also very nice. It still gives a 8hours usage after full charge. Its charging speed is also very fast. Full charge takes less than 2 hours. This is the best Laptop for professional use.
