"Putting the Nokia N79 (metaphorically) next to the original N73 is instructive - not only has the specification dramatically improved in the intervening three years, it's smaller, sleeker and lighter and is a testament to the onward march of technology. Putting the N79 next to the N78, it's closest living relative, is also instructive, in that the N79 is smaller and higher specification again, and with a more normal design to boot. Rafe's commented at length on the positioning of the N79 and N78 in the article linked above, so I won't repeat it."
