I'm a slingbox owner and a former hulu plus subscriber. Hulu plus sucks, it's a long list of old crappy shows. It's frustrating not having access to everything hulu has access to.
Also, with the slingbox, if I'm working in the garage I can bring a laptop out there and it's instant tv. If I'm playing xbox, I can set the laptop next to me and peek in on the baseball or football game. Also, with ondemand, the library of shows I have on demand access to is much better than hulu. I guess I got my fill of 80's tv in the 80's.
However, the iPhone sling app has a **** interface. Also, navigation is slow and clunky. I usually use the zap2it tv guide app, find what I want to watch, then direct tune the sling app. It would be REALLY nice if it worked in the background. This app hasn't been updated in a long time.
Yeah I just cancelled my Plus membership, no need for it now. I agree the Iphone app needs updating and badly, it works ..just.
