Now that I have both units its easy to tell the new style with the larger hard shell is slimmer and lighter than the early Ltd. edition style. It seems however the Ltd edition hard shell holds on to the phone better than the newer version. The difference between the two besides the hard shell being larger and covering most of the phones back on the new design is that the rubber portion is much thinner on the new model vs the Ltd edition model. Also I find that the hard shell of the newer model seems somewhat loose fitting on the phone vs the Ltd edition model. I do like having a color choice, I chose dark blue and the fact the thinner rubber sleeve makes the case less bulky. I'm not sure of the one I like better because the loose fitting shell mostly on the left side has me worried its going to slip off. Time will tell. More later on this case.
