Just some days ago I tried to sign up to Hulu on my wife's macbook and suddenly the input fields didn't work anymore. It's probably a bit of an outdated version (10.x), but still.
Looks like they are back on track. I like the renaming of the upcoming release. A little sad to see Unite go. Perhaps it wasn't the right time - it always looked like a bit of a security nightmare.
Open services should be easily accessible/usable in the OS layer and across networks, but I guess they currently aren't - without some skill.
If I take my laptop around someone's house and want to share a few files - how easy is this? If I want to just play some tunes, or a video from my laptop on someone else's PC or set top, how trivial is it? Not very. At least not for the mythical average user.
A decentralised web sounds good to me also. And lowering the barriers to web publishing where you have control over the content in my eyes is a good thing.
Unite though feels like a component that could live happily outside of the browser (again ideally in the OS layer). The email client could be standalone also. Unless they want to go the Chrome OS way.
