I think MU would have gone higher today if not for the overall weakness in the US stock market. It hit $63.98 before the Dow really started to tumble. I see the restraining of the stock price as a buying opportunity, but tomorrow might be another down day as Asian stocks look like they're going lower as global uncertainty has re-surfaced, particularly in Italy, and the rest of the European economy looks weak as well. Things aren't so great in other parts of the world either.
As to SNES, you're right. Their path to profitability is unclear, dubious. I jumped in too quickly, but I've finally learned my lesson in regard to buying sub-$5 penny stocks.
