Depends what you mean by fuzzy. Compared to my MBP the webcam on the MBA is quite 'fuzzy' because it is much lower resolution. There is quite heavy image noise.
I got a new deluxe MBA gen 2 today and all seems good.
apart from a fuzzy webcam.
considering what I could have had ... am i just lucky?
The image just isn't as crisp as on the relatively state of the art camera in the larger laptops. It is perfectly usable, it just uses a lower resolution (megapixel) camera.
