Sorry but that's a bunch of crap.

I can mine all n factors just fine on gpus that are out NOW.  (Correct, you can get 2.5Kh/s on Yaccoin with 1 single gpu out of all made;  What are you going to mine with in 55 days?)
Even more so, higher n factors start to normalize hashing power between devices of different price ranges so in the end it's better for descentralization, takes the power away from the huge scrypt farm operators and back into the little guy with a cpu and a bunch of cheaper gpus. (at least till the big guys start to figure out they need different hardware for optimal results) (Huge farms leave if there's no profitability, I would not tout that as a plus.  For the "little guy"  he will need to buy new hardware too, GPU, CPU and / or RAM;  why would the little guy with low funds put in more money when they can just mine 100's of others without?).

Your statements are not correct, and I can prove them wrong really easily, at least on the hardware side. (this post has no proof, so yes please provide refutation to my points)
Yac has been around for a long time now, and it has battled the insta-mine burden for a while, lots of negative press...but it's still a pretty solid coin, and excellent for small time miners. (agree)

"-have no long-term network security" -> this just got invalidated. (how might I ask) Anyone can solo mine a coin with higher n factors, at least way easier than solo mining a scrypt coin or something like vertcoin which attracted all the farm dudes of the world (they are all lazy and have tons of outdated hardware at their disposal).  (again, the fact that you can solo mine is NOT something you should tout as it's Bad.  This meas poor network hash rate and thus poor network security.)
