Word got out today from Reuters that Xiaomi CEO Lei Jun spoke with Facebook's Mark Zuckerberg about a potential investment seen back in October, but no terms were set in stone. Xiaomi started off as a business that sold smartphones at a low cheap cost. Those that are in business know that you can't make a profit selling at cheap margins. Apparently those that do know business, didn't know that you can actually make a killing by doing just that - and exactly how Xiaomi executed its success. Now one of the largest growing companies for smartphones and other small gadgets, the company is valued at $45 billion.
