SlingPlayer lets you control and stream shows from your set-top box over Wi-Fi or 3G — assuming you've already purchased a $180 Slingbox. Sit in your hotel room in Kuala Lumpur and use your phone or tablet to watch Community as if you were at home on the sofa. It's the most complete TV-on-the-go solution available.
WIRED Can stream from your DVR and Apple TV, too.
TIRED Expensive. Doesn't play friendly with the family room; changing the channel remotely changes it at home, too.
