I have been looking at the 320 for awhile and have reconsidered the 480 and 320c due to this thread.
Based on the specs the 320 and 480 both have larger screens than the 320c. The 480 also has 50% more resolution than the 320. Does this not help? It sounds like the color option might be worth more than screen size and resolution. The attached specs were copied from
