Microsoft’s Zune senior business development manager Dave McLauchlan recently said he is leaving the company to create his own startup. McLauchlan announced his resignation to the public on Twitter. “I have some news to share,” he tweeted. “Last week I offered my resignation to [Microsoft] and my last day is [Friday].” McLauchlan will work on a startup called “Buddy.” The website, located at http://Buddy.com, says the company will help developers “build mobile apps cheaper, faster and easier.” McLauchlan also tweeted that he will still be around in the mobile space. Microsoft killed its Zune mobile media player earlier this year, but Microsoft confirmed it will continue to offer music and video services on Xbox LIVE, Windows PCs and Windows Phone devices.
