I'd bide my time on this. Allowing another company to make a similar, cheaper, but of a lesser quality product can often have a beneficial impact on the original product. In this case users that may have been prohibited by the Mac price tag may be able to pick up a product with a similar/same OS and begin to use it. Down the line these consumers may like the product and decide the next time to spend a little extra to get the "good" one. Worse comes to worst Apple can always enforce its EULA, which would be interesting because you don't often see those types of court cases, and can regain their market share.
