Me too, I am considering to leave the macbooks (sadly) to support my principles but it is not an easy task to find a company that threat their workers better.
Because this thread is becoming heated, I am going to bow out. But before I do, I looked into how companies reacted after the 2009 Foxconn stories and based my decision on who reacted, what they admitted, and incidents associated with them since then. Remember, not all Foxconn employees are forced to work with the same chemicals or conditions. Also, Toshiba doesn't use them at all. (I went with another brand, but am walking away because the Apple fanboys are in a mood today...)
