oh and there is!
Now more than ever and people like you are one of the reasons for it. But it ain't gonna be litecoin or anything else presented here and if it comes bitcoin will be crushed. There are alot of skilled people out there watching this development, and if they think bitcoin gonne become nasty they'd write something better.
Not a clone but software which shifts the paradigm from "I got in b4 you so I own your ass' to something were people would actually engage in creating the crypto-economy that the idea was initially aimed at. The currency aspect would only be a minuscule part of the project with implications beyond anything you have thought were possible.
Without your kind Bitcoin could even become that part, too bad...
If the answer is no there is no reason for buyers/sellers to use xCoin. Things like cpu vs gpu is immaterial. Things like "yeah I get to mine when difficulty is low" is equally immaterial.
If you only repeat that often enough it will become true.
Protip: Forks without premine and malicious intent like NMC and LTC actually support bitcoin, its appeal and to the end what people are willing to pay for it.
