I've had it from day one and have been very happy with it. I know some complain about the price but I see it this way. For me, $10 per month is a small price to pay for all the quality programming on offer.
Basically it has all the best new shows from all the US "premium", (ie paid for) channels. That is, HBO, Showtime, Starz, Cinemax, as well as shows cherry picked from other networks like AMC and BBC.
To subscribe to those four premium channels in the US costs US$55 per month (from DirecTV). Now OK, each of those is a package of several TV and movies channels and not just a single channel like SoHo, but you would still have to subscribe to all of them to see all of the shows that Sky has packed into Soho :)
Added to that, is that many new shows will be likely played near their US air date. Looks like Luck will be 2 weeks behind and hopefully Game of Thrones season 2 will be the same or sooner when it starts in the US on April 1st :)
Then you have replays of classic older series, (am loving Six Feet Under which I missed originally), and all in glorious HD.... I'm sold :)
I'll go now before I start sounding like a Sky salesman.... Ooops! Too late!
