You know also that Bitcoin was supposed to be mined by many different CPU processors in its beginning and it was not envisioned that people would make pools, fill warehouses with GPU and try to develop ASIC for it? It's not because that the ending result is not the same as the original vision that the project is worthless.
Anyway, my belief is that the value of Litecoin is not by looking at Litecoin alone, but depending of its relation with Bitcoin. I think the real value is what you can do between multiple blockchains, and how blockchains can be adapted for different needs. Bitcoin is only a couple of specific parameters for the concept of crypto-currencies and doesn't make it better or worse than having different parameters for the same concept. There's a lot more potential with multiple crypto-currencies than sticking only with one.
Bitcoin was supposed to be mined by few large competing datacenters, so with more specialized hardware, it's right on track.
I don't really see what Litecoin has to offer. It has more coins, and shorter time between blocks, but the coin value is relative, so the number doesn't matter, and shorter block times don't offer any security advantages, so... It's just Bitcoin with less support.
