Boxee has a new TV box-top device that will hit Walmart tomorrow and cost $99. Unlike its competitors, Roku and the Apple TV, it offers a live TV tuner and a DVR without a storage limit. The “No Limit DVR,” however, costs $14.99 a month. Tough space for Boxee – smart TVs are increasingly adept at doing the same thing, and Apple is likely working on a “TV to rule them all.” [Source: TechCrunch]
