Microsoft is no stranger to industry flak, but it's always better to give than to receive, right? Steve Ballmer thinks so, and in a recent Bloomberg interview, he took a second away from talking up the new Office 2013 to smite Dropbox, saying that the 100 million users it boasts "sounds like a pretty small number to me." He recovered slightly by adding "I'm not beating on Dropbox," only to follow it with the finishing blow: "They're a fine little startup and that's great." We doubt anyone else would call Dropbox a startup at this point, but Microsoft's chief can't be seen complimenting a SkyDrive rival now, can he? After having to defend the user stats for Redmond's Yammer, he was also quizzed on the undying native Office for iPad rumor, to which he had "nothing to say," apart from "we'll see what we see in the future." If these snippets aren't quite enough, then head to the source link for the full interview. Ballmer may be a little less shouty these days, but it's good to know he's still capable of delivering the odd high-caliber burn.
