@chunker: every cloud miner has an ROI based on the cost of the hashpower and the amount of the rewards.  So if you don't like saying they "offer" ROI or whatever, it's just semantics.  The point is that historically, during given time periods, an investment in scrypt.cc yielded a total return on one's investment in a given time frame and looking forward you can calculate projected ROI based on current reward amount and the price you paid for your hashpower.

This is obvious stuff we all know and anybody can see that's what I meant when saying a certain ROI is "offered."
