If the latest issue of Forbes feels a little heavier on the newsstand this week, that's because there's an actual Wi-Fi hotspot inside. A new print campaign for Microsoft's cloud-based Office 365 service is giving selected Forbes readers 15 days of free T-Mobile Internet access with a wireless router small enough to fit in a cardboard insert. The tiny hotspot's battery will last for about three hours, but there's an included micro-USB port to recharge the ad. Judging by the photos and videos online, it looks like most readers' response was to immediately rip the ad apart.

This isn't the first time a print ad tried to cross over into the digital world. Last October the CW Network managed to embed an actual smartphone in an issue of Entertainment Weekly to display tweets promoting their fall schedule. [via DesignTaxi/Slick Deals]
