Really? LTC currently run for roughly 0.004 BTC each. At 12 USD/BTC that's just under 5 cents each. Take into account that both chains are showing no signs of weakness and that LTC topped off at over 0.007 BTC each and you have a reason to want them. If nobody did then they wouldn't even be traded...a week or so ago volumes of BTC/LTC trade on Vircurex alone were topping 40 BTC a day (I didn't check BTC-e.) Even if it's little more than speculation fodder (which I think it is more than) it is being adopted.
