Are you a Verizon FIOS customer? If so, you now have access to HBO Go. This is the latest step in cable's “TV Everywhere” plan. Drop by the HBO Go website and you'll be treated to over 600 hours of movies and TV shows, all of which you can stream live (and some of which you can stream in HD). TechCrunch reported on the service earlier today.
According to Michael Arrington, HBO Go is good, but not great. The choice of shows and movies was fairly limited, and the service is pretty unnecessary if you actually have an HBO subscription. The On-Demand function won some kudos, and the site looks good, but overall the service is not a 'must have'.
I suspect that HBO Go will be fleshed out a lot more by the time it is ready for a larger release. If they aren't going to offer the same shows streaming that they do over the television, this TV Everywhere plan isn't going to work out too well. Got FIOS? If so, give HBO Go a trial and let us know what you think.
