New submitter shirleymarone sends word that investors are becoming impatient with Amazon's willingness to absorb short-term losses for theoretical long-term gains. The company brought in over $19 billion in revenue last quarter, but reported a net loss of $126 million. The company warned of even greater losses this quarter. Amazon officials exude a serene if vague confidence. "We're not trying to optimize for short-term profits," Thomas J. Szkutak, the chief financial officer, said in a conference call. "We're investing on behalf of customers and share owners," he said. "We're fortunate to have these opportunities." But even the analysts, who are generally enthusiastic about the company and its global ambitions, are asking slightly more pointed questions these days. For all these investments, one analyst asked Mr. Szkutak, why are sales not increasing even faster? His answer: Just wait. ... Amazon, which is based in Seattle, long ago transcended its roots as a simple retailer. In recent weeks it introduced Zocalo, a document storage and sharing service that grew out of its fast-growing web services division. It began a program to allow readers to consume as many e-books as they want for a set monthly fee. And it is starting to ship its long-awaited entry in the smartphone sweepstakes. The phone, the result of years of development by thousands of Amazon programmers and designers, is meeting some resistance from reviewers.
