HBO Now launched today, just in time for Game of Thrones.

Can sign up using a US iTunes account, as I believe they have an exclusive deal with Apple for the first 3 months before it expands to more platforms. I think you have to sign up on an iOS device or Apple TV, but then you can watch it online in the web browser on a PC or Mac.
I tested it this morning using a VPN as UnoTelly haven't unlocked the channel just yet (hopefully should be soon as Unblock-US seem to have unlocked it already) and it works well. My friend says it works well with Chromecast too, but I didn't get a chance to check before I went to work.
It's $15 US a month, but there is a free month trial. I hope once it launches to more platforms they add more payment options other than iTunes.
Is anyone else going to try it out?
