Update 2010 - Naithon is more heavily developed now, but compared to the main beaches (Patong, Karon, Kata) it's still much quieter.
It's not a long beach, you can walk from one end to the other in about 10 minutes. The sand is slightly squeaky. We like this area of Phuket, away from the main tourist beaches. The hills are still green, and the valleys are full of rubber plantations. The roads wind up and down, the views are sometimes stunning... Naithon beach is a great place to stay if you like it quiet. We stopped there last week for a walk on the beach and a bit of lunch. In the restaurant only 2 tables were occupied, the food was decent (nothing flashy here) and despite being by the road, it was peaceful. There's not much traffic, though most of what we saw was building related, so if more construction starts, Naithon could get noisier. Time to make hay while the sun shines...
