The DVR’s full potential may have finally been realized now with the TiVo Roamio ($200-$600 depending on the model). New to TiVo’s game is Wi-Fi and the ability to watch all your saved shows and movies on iOS devices that are running the TiVo app. With new faster processors, the power to record up to six shows simultaneously, and hefty hard drives that can store up to 450 hours of high def video, this may be the last DVR you need before the government requires U.S. citizens to shove TV tuners up their nostrils.
