We really thought we liked Sling. Not anymore…They just became another greedy media company in one very poorly thought out move. Sling is only allowing users of its more expensive products to use the upcoming iPhone client. Slingbox, Slingbox AV, and Slingbox TUNER owners won’t be able to use their Slingboxes on the iPhone or iPod touch. They will need to buy some of the more recent hardware (with a $50 discount). Poor form Sling, very poor form. Image below.
