A touch-optimized version of Microsofts flagship productivity suite will be landing on the iPad before it arrives on the Surface or any other Windows-powered slate for that matter. An Office app of sorts is already available to download for free for the iPhone — free because it needs a paid-for Office 365 subscription to work thoroughly — but until now there has been nothing available for tablet owners who want to get productive. However, an iPad version of Office is expected to debut in the App Store before the end of July. According to ZD Net, which was the first tech publication to reveal the existence of the iPhone app and its launch date, Microsoft has decided to get a version of Office out for the iPad ahead of one for its own tablet devices and the launch date has moved forward.
