Just Hulu released their new app, and the Android app, was missing, and they keep blocking it for us that can use flash on our phones
It'll make its way to Android sooner or later. Many developers are seeing the potential of Android. IMDB came out today for Android, which was the last big app I was missing from my move from the iPhone.
As for Hulu, I have it working just fine on my Nexus One, by changing the user agent string and watching in Flash. But I'd much rather just load it onto a MicroSD card or stream off Slingplayer.
