In its quest to never be outdone in the features wars, Microsoft has drifted into the habit of bundling its most impressive new capabilities as peripheral trinkets. But in the case of SharePoint 2013, they’ve set a new record for understatement. Yes, SharePoint 2013 is feature-rich almost to a fault, and yes, most of the new stuff is big-banner game-changing (Social computing! SharePoint-in-the-cloud!). But some of the most powerful items are geeky little widgets that barely get a mention on TechNet, and when it comes to SharePoint 2013, the In-Memory BI Engine tops the list.
