I don't have any Litecoins, but I am starting to see how they are an improvement to bitcoin.
Bitcoin seems to be advancing rapidly into an arms race of specialized chipsets that make previous models obsolete in less then a year (as in not competitive on the hash/energy rate)
This means that miners will have to be more and more capable of taking on large risk and larger capital expenses, which is forcing the small guys out, and forcing all miners into pools.
The result of this is that the political power over the blockchain is being concentrated into fewer and fewer hands.
This is bad.
Bad to the point of eventually all power will be in the hands of a few very rich people, and they will be able to lead the rest of the community by the nose.
With litecoins, it is still within everyone's reach to independently mine, and when you mine, even if you have less fancy equipment, the energy you put into hashing will be about the same as the bigger guy along a fairly linear measure.
This is great news, because trying to change the direction of the currency would go up against a much larger population of miners that will need to be convinced.
Take a look at
http://blockchain.info/ and see how few pools there are that write all of the blocks. This is a lot of power in a few hands, and that is dangerous.
