Excerpt: Which consumer product first enabled any PC with an Internet connection to remotely control a set-top box or DVR and stream live or pre-recorded television to it? If you answered “Slingbox,” you’re mistaken. It was actually Sony’s LocationFree TV.
Pros: Acts as a wireless client; two IR ports; can stream to PSP.
Cons: Why would you need to stream to a PSP? Low-resolution; no smartphone client.
